Answer:
<h2>x = 0</h2><h2>y = - 2</h2>
Step-by-step explanation:
-5x + y = -2………… Equation 1
-3x + 6y = -12 ………… Equation 2
Using substitution
Make y the subject in equation 1 and substitute it into equation 2 and solve for x
That's
y = 5x - 2
We have
- 3x + 6( 5x - 2) = - 12
- 3x + 30x - 12 = - 12
27x = - 12 + 12
27x = 0
Divide both sides by 27
x = 0
Substitute x = 0 into y = 5x - 2
We have
y = 5(0) - 2
y = - 2
So the solutions are
<h3>x = 0 </h3><h3>y = - 2</h3>

Answer:
m = -1 (answer (a))
Step-by-step explanation:
Recall that the slope of a straight line is m = rise / run.
As we go from the point (0, -2) to the point (2, -4), we see an increase of 2 in x and a decrease of 2 in y.
Thus, the slope of this line is m = rise / run = 2/(-2), or m = -1 (answer (a))
