find an equation of the line containing, (4,-2) and parallel to the line containing (-1,4) and (2,-3)

Question

find an equation of the line containing (-1, 3) and perpendicular to the line containing (3,-5) and (-2,7)

Answer 1

You have to find the slope of the other line.

On the second: slope= changey/changeX
= -5-7 / 3+2=-12/5

On the second, perpendicular means the new line has a slope of 5/12.
