Answer:
the slope is -2/1
Step-by-step explanation:
(10,-9) and (3,5)
y2-y1/ x2-x1
5-(-9)/3-10
14/-7
Answer:
35
Step-by-step explanation:
Step-by-step explanation:
Substitute the y in the 1st equation with the 2nd equation.
7x + 10(2x + 9) = 36
7x + 20x + 90 = 36
27x + 90 = 36
3x + 10 = 4
3x = -6
x = -2
So now we can find y.
y = 2x + 9 = 2(-2) + 9 = (-4) + 9 = 5.
So x = -2, y = 5.
