Question

What is the value of y if the line through the two given points is to have the indicated slope (4,y) and (2,6), M=-4?

Answer 1

y= -2

Explanation:

y2-y1 6-y = 8

x2-x1 2-4= -2

To solve for y : Your answer has to be 8 then you divide 8/-2 = -4

6-y=8

subtract 6 from both sides = -y =2

multiply each side by(-1)

to remove the - from Y (-1)y =(-1)2

y =-2
