Question

A line with slope -3 passes through the points (5,2) and (9,y). Find y. (and yes I know this is a repost but the other one was wrong its not y=5)

Answer:

y = -10

Explanation:

Using the point-slope form of the equation for a line, we can write the equation as ...

y -k = m(x -h) . . . . . line with slope m through point (h, k)

y -2 = -3(x -5)

Using the values for the other point, this becomes ...

y -2 = -3(9 -5)

y = -3(4) +2

y = -10
