Equation 1) y = -2x - 6
Equation 2) y = x + 9
Move equations around, by moving the (x)s to the left side of the equation so that x and y are on the same side.
To do so, add 2x to both sides in equation 1, and subtract x from both sides in equation 2.
1) 2x + y = 6
2) -x + y = 9
Subtract equations from each other.
3x = -3
Divide both sides by 3.
x = -1
Plug in -1 for x in first equation.
y = -2x - 6
y = -2(-1) - 6
Simplify.
y = 2 - 6
y = -4
(-1, -4) ==> x = -1, y = -4

Answer:
$48
Explanation:
24 Divided by 5 = 4.8 times 10 =48
Answer:
Step-by-step explanation:
Okay, so first of all, when a slope is negative, the line goes down from left to right, not up from left to right. Then, plot the Y intercept as -2. Finally, either go up 2 and left 3 or down 2 and right 3.
