Use the slope of the formula to find the missing coordinate. m=3/5, P (3,2) and Q (8,_)

-1

1

5

Given m=3/5, P (3,2)

For Q (8, y)

first find the difference in x between P & Q

x = (8-3) = 5

Multiply by the slope 3/5

5*3/5=3

Add to the y-coordinate of P

Q (8,2+5*3/5) = Q (8,2+3) = Q (8,5)

So the missing y-value is 5
