I'm assuming it is -m, +m, -m, +m etc..
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:

Let x be the amount invested at 7% and y the amount invested at 6%
We know that the yearly interest earned = 0.07(x) and 0.06(y)
x+y =4500
0.07x +0.06 y =290
Solving the equations will give , x = $2,000 and y=$2,500
Answer:
4/3
Step-by-step explanation:
Slope is rise/run so find two points and find the rise/run. (0,-1) and (4,2) so the slope would be 4/3
