Answer:

Step-by-step explanation:

The equation is

y = 0.2x + 17......(1)

Let point A(a,18)

X1 = a and y1 = 18, slope m = 0.2

y - y1 = m(x - x1)

y - 18 = 0.2(x - a)

y - 18 = 0.2x - 0.2a

y = 0.2x - 0.2a + 18.......(2)

Equating (1) and (2)

0.2x + 17 = 0.2x - 0.2a + 18

0.2x - 0.2x + 0.2a = 18 - 17

0.2a = 1

a = 1/0.2

a = 5

So A(5,18)

Let B(25,b)

Slope m = (y2 - y1)/(x2 - x1)

y2 = b, y1 = 18, x2 = 25, x1 = 5

0.2 = (b - 18)/(25 - 5)

0.2 = (b - 18)/20

Cross Multiply

b - 18 = 20(0.2)

b - 18 = 4

b = 4 + 18

b = 22

So B(25,22)

A(5,18) and B(25,22)
