I'm don't understand

Question

consider the following two lines. The first passesthrough the points (-2,-4) and (1,2). the second line passes througt the point (1,1) and is parallel to the frist line. Find an equation for the second line

Answer 1

you CAN understand, because the two lines will have the SAME SLOPE (because parallel).

 

so for the second line, use the point slope form because you have a point and you can calculate the slope (of other line determined by its two points).
