Answer:

x=-5, y=2. (-5, 2).

Step-by-step explanation:

2x+y=-8

5(2x+y)=5(-8)

3x-5y=-25

10x+5y=-40

3x-5y=-25

What is the equation of the line that passes through the point ( -8,-7) and has a<br>slope of 1?​
Pani-rosa [81]

Answer:

y = x+1

Step-by-step explanation:

We can use

y = mx+b where m is the slope and b is the y intercept

y = 1x +b

Substitute the point into the equation

-7 = 1* (-8) +b

-7 = -8+b

Add 8 to each side

-7+8 = -8+8+b

b = 1

Put this back into the equation

y = x+1
