Question

Use the slope formula to find the missing coordinate.

m= 3, P(3, 2) and Q(8,_)
O-1
1
05

Answer 1

Let the missing value = x

Slope is the change in y over the change in x:

3 = (x-2)/ (8-3)

3 = (x-2) / 5

Multiply both sides by 5:

15 = x-2

Add 2 to both sides:

X = 17

The missing coordinate is 17
