Objective A – To find the equation of a line given a point and the slope
The equation of a line can be written in the form , when a point on the line and the slope of the line are given.
If given a point, and the slope, , then the equation can be written in Point-Slope Form: then rewrite into the slope-intercept form by solving for
Objective B – To find the equation of a line given two points
If given two points on the line, first find the slope between the two points. Then use the same method for a given point and slope.
Here is a worksheet to practice using the point-slope form of the equation of a line.
