Point-Slope Form Given a point(x1,y1)(x1,y1)and slopem, point-slope form will give the following equation of a line: y−y1=m(x−x1)y−y1=m(x−x1) Now that we know both the slope-intercept form and the point-slope for linear equations, when we are asked to find an equat...
Find the equation of the line that passes through the points (−2, 4) and (1, 2).I've already answered this one, but let's look at the process. I should get the same result; namely: y=−23x+83y=−32x+38 Given two points, I can always find the slope: m=(4)−(2...
However, the slope only describes the angle or gradient of the line, but not its position on a graph. The most common way to describe a line is with an algebraic equation. There are several standard equations for a line: point-slope form, slope-intercept form, and standard form. ...
Equations of a Line in \mathbb{R}: There are three equations for a line in \mathbb{R}: 1) General equation:AY+BX+C=0. 2) Point-slope equation:y−y0=m(x−x0). 3) y-intercept equation:y=mx+b,m,b∈...

The point slope form calculator, formula, example calculation (work with steps) and practice problems would be very useful for grade school students (K-12 education) to learn what are different equations of a line in geometry, how to find the general equation of a line. They will be able ...
For example: Write the equation of the line that passes through the points (−3, 11) and (−5, 15).Solution 1. The direct method. The only difference between this problem and the previous one is that, here, we must calculate the slope. We did that for those two points in ...
