Find the equation of a line through the points (-2,1) and (3,6)
(-2,1) and (3,6)
First, let's establish slope.
Slope is the change-of-y divided by the change-of-x.
Let's take one point and use the point-slope formula. I randomly select the first point, (-2,1)
Subtracting a negative number is the same as adding a positive number...
Let's add 1 to both sides...
Let's apply the other point, (3,6), to verify...
