Answer:
B. only (-2, 9)
Step-by-step explanation:
A graph of the equation makes it easy to see that (-2, 9) is a solution and (2, -9) is not.
You can try these values of x in the equation to see what the corresponding y-values are.
y = -2{-2, 2} +5 = {4, -4} +5 = {9, 1}
Points on the line are (-2, 9) and (2, 1).
(2, -9) is not a solution.
Answer:
y =
Step-by-step explanation:
with the point slope form, plug -9 (x coordinate) into x1, -3 (y coordinate) into y2, and -4/3 (slope) into m
y - y2 = m(x - x1)
y - (-3) = -4/3 (x - (-9))
y + 3 = -4/3 (x + 9)
y + 3 = -4/3 x + -12
y = -4/3 x - 12 - 3
y =
