Question

What coordinates do I plot at

Answer 1

Explanation:

y - 10 = -2(x - 10)

y - 10 = -2x + 20

y = -2x + 20 + 10

y = -2x + 30

When x = 0 ; y = 0 + 30 = 30 ; (0,30)

When x = 10 ; y = -2*10 + 30 = -20 +30 = 10 ; (10 , 10)

When x = 5 ; y = -2*5 + 30 = -10 + 30 = 20 ; (5 , 20)

Plot ( 0 ,30) ; (10,10) & (5,20)
