Y=mx+b
mx=slope
b=the y intercept
y= value of y in this equation
It means that you have to find the solution of the systems of equations.
Answer:
the answer to 5x-7(2-4x)= =33x−14
the answer to 8 - 3(6 - 6x) ==18x−10
the answer to 9a - 4(2a + 5) ==a−20
Step-by-step explanation:
First find the slope using
(y2-y1)/(x2-x1)
(1-2)/(3-1)=-1/2
Since only one answer has s slope of -1/2 the answer is B
