Extra Credit Reading 4. It looks like they gave you two to pick from here. Look at the slope-intercept and general forms of lines. We know we are looking for a line parallel to.

Note also that it is useful to pick a point on the axis, because one of the values will be zero. It is simple to find a point because we just need ANY point on the line.

Then the slope is: The point slope form gets its name because it uses a single point on the graph and the slope of the line. Slope-intercept form But, could we do better? And of course, if you need more help, feel free to ask the volunteers on our math help message board. You have all the information you need to draw a single line on the map.

Find the equation of the line that passes through 0, -3 and -2, 5. As you can see, point-slope form is nothing too complicated. Point-slope form is all about having a single point and a direction slope and converting that between an algebraic equation and a graph. It is just one method to writing an equation for a line.

The process for obtaining the slope-intercept form and the general form are both shown below. Now substitute those values into the point-slope form of a line.

Since you have a point and a slope, you should use the point-slope form of a line. This type of problem involves writing equations of parallel or perpendicular lines. The strategy you use to solve the problem depends on the type of information you are given.

Using the Point-Slope Form of a Line Another way to express the equation of a straight line Point-slope refers to a method for graphing a linear equation on an x-y axis. If is parallel to and passes through the point 5, 5transform the first equation so that it will be perpendicular to the second.

You may be wondering why this form of a line was not mentioned at the beginning of the lesson with the other two forms. That means that number will stay the same. This is the equation of the line in a form called slope-intercept form.

How much did x change? How is this possible if for the point-slope form you must have a point and a slope?

Now that you have a slope, you can use the point-slope form of a line. Find the equation of the line that passes through 1, -5 and is parallel to. Given Two Points When you are given two points, it is still possible to use the point-slope form of a line.

To get b, all you do is take your point and slope and use this equation: We know how to use the point-slope form, so the final answer is: Do the arithmetic, and this will give you the value of b. Point-slope form is one approach for finding a line and it requires two things also:Algebra > Lines > Finding the Equation of a Line Given a Point and a Slope.

Page 1 of 2. Finding the Equation of a Line Given a Point and a Slope. If we have a point, Finding the Slope of a Line from Two Points. Linear Equations. Graphing Overview. Finding the Slope of a Line from the Equation. Write the Slope-Intercept Form equation for the line with slope = 2 and passing through (2, -1) y=2x-5 Write the Slope-Intercept Form equation for the line with slope = -1/3 and passing through (4, -3).

The slope intercept form calculator will find the slope of the line passing through the two given points, its y-intercept and slope-intercept form of the line, with steps shown.

Show Instructions In general, you can skip the multiplication sign, so `5x` is. This is the equation of the line in a form called slope-intercept form.

In slope-intercept form, the slope is still -2/3, and the place where the line intercepts the y-axis is 13/3. Hope that helps a bit! Mar 08, · Slope-intercept form follows the format y=mx+b where m=slope and b=y-intercept. So, given the two points, you can calculate the slope by using the formula m=(delta y)/(delta x) By the way, delta means change killarney10mile.com: Resolved.

Equation of a straight line can be calculated using various methods such as slope intercept form, point slope form and two point slope form.

Two Point form is one such method used to find the equation of a straight line when there is no slope and the straight line is in a Cartesian plane passing through two given points.
