Answer:
It only has one solution
Step-by-step explanation:
Y-y1 / x-x1 to get slope
5 - 1 / 9 - 4
m (slope) = 4/5
plug in one point to get b
1 = 4/5(4) + b
1 = 16/5 + b
b = -15/5
y = 4/5x - 15/5
Answer:
x² + 6x-27
Step-by-step explanation:
(x+9)(x-3) (expand by distributive property)
= x(x) -3(x) + x(9) -3(9) (simplify)
= x² -3x+9x-27
= x² + 6x-27
