1). (B). Replace one equation with the sum/difference of both equation.

System B is

-4x + 3x = - x

- 6y + y = - 5y

9 - 4 = 5

- x - 5y = 5 ........ <em>(2B)</em>

Which equation has a slope of –52 and a y-intercept of –2?
kicyunya [14]

Answer:

I'm sure there might be a typo in the question (AKA the slope is -5/2)

but the answer would be

D

Step-by-step explanation:

y= mx+ b

where m is the slope, and b is the y intercept

y= -52x -2

..........

5x + 2y = –4

2y= -5x -4

y= - 5/2x -2

y =  -  \frac{5}{2} x - 2
