Let me = slope

m = (18 - (-2))/(4 - 0)

m = 20/4

m = 5

We now plug slope 5 and one of the given points into the point-slope formula.

y - y_1 = m(x - x_1)

y - 18 = 5(x - 4)

y - 18 = 5x - 20

y = 5x - 20 + 18

y = 5x - 2

Done!

Answer:

Step-by-step explanation:

6/4=(6-1)/(4-x)

6/4=5/(4-x)

6(4-x)=4(5)

24-6x=20

-6x=-4

x=4/6

x=2/3
