Multiply the first equation by -2 to eliminate a variable so it becomes:
-12x+8y=48
4x-8y=-32
Add them together.
-8x=16
x=-2
Plug it in one equation.
6(2)-4y=-24
12-4y=-24
-4y=-12
y=3
Ordered pair is: (-2,3)
Answer:

Set up the equations then solve
Answer:
m = 4/3
Step-by-step explanation:
To find the slope of a line use the formula, where "m" means slope:

*You don't need to show this part on paper*
Choose which point you want to be point 1 and point 2. Remember the points are written (x, y).
Point 1: (-2, 1) x₁ = -2 y₁ = 1
Point 2: (4, 9) x₂ = 4 y₂ = 9
Substitute the coordinates into the formula:
*Show this part on paper*

Simplify
Reduce by dividing by 2
Slope
The slope of the line is 4/3
$1.08
you would multiply your cost (1.00) by 8% which is equivalent to .08 and then add to to the original cost. or to skip the middle step just multiply it by 1.08 since you are adding the 8% to 100% of the original cost
