Answer:

B

Step-by-step explanation:

16(-5) - 7 = 11(-5) - 32

-80 - 7 = -55 - 32

-87 = -87

-4(-5) - 10 = 2(-5) + 20

-30 ≠ 10

Answer:

c. Both A and B

Step-by-step explanation:

Let's solve the equations to find out.

Equation A

16x - 7 = 11x - 32

5x - 7 = -32

5x = -25

x = -5

So, Equation A has a solution of x = -5.

Equation B

-4x - 10 = 2x + 20

-6x - 10 = 20

-6x = 30

x = -5

And so does Equation B.

Find the slope of the line that passes through (-2,-3) and (1,1).
Serga [27]
Slope formula : (y2 - y1) / (x2 - x1)
(-2,-3)...x1 = -2 and y1 = -3
(1,1)...x2 = 1 and y2 = 1
time to sub and solve
slope = (1 - (-2) / (1 - (-3) = (1 + 2) / (1 + 3) = 3/4 <==
