Question

The slope of AB is 2/3, A(1,-4) and B(-5,y). Solve for the value of y.

Answer 1

y=5

Explanation:

the difference between the x coordinates of each point is 6. in order for the slope to simplify to 2/3 the difference in y should be 9.

y=9-4(y coordinates of A)

=5

Answer 2

y=5

the difference between the x coordinates of each point is 6. in order for the slope to simplify to 2/3 the difference in y should be 9.
y=9-4(y coordinates of A)
=5
