Answer:
2 solutions.
Step-by-step explanation:
Rearrange the second equation:
-8x - 4y = -20
-4y = 8x - 20
Divide through by -4:
y = -2x + 5
and our first equation is
y = 2x - 5
Subtracting the 2 equations
0 = -2x -2x + 5 -(-5)
0 = -4x + 10
x = 5/2
and y = 2(5/2) - 5 = 0.

Answer: Slope = -3/7</h3>
===================================================
Apply the slope formula
m = (y2-y1)/(x2-x1)
m = (6-3)/(-9-(-2))
m = (6-3)/(-9+2)
m = 3/(-7)
m = -3/7
This means each time you go down 3 units, you go to the right 7 units.
Slope = rise/run = -3/7
rise = -3 and run = 7
36 / 10 = 3.6 as a decimal ;
