Answer: (-9,18) , (1,8) and (5,4)
Step-by-step explanation:
If the x coordinate is -9 then plot it into the equation and solve for y.
y = -1(-9) + 0
y = 9 + 9
y = 18
Same for the second one plot in the value of x and solve for y
y= -1(1) + 9
y = -1 + 9
y = 8
Again same for the last one
y = -1(5) + 9
y = -5 + 9
y = 4
