We can use the slope formula:

$\frac{y.2 - y.1}{x.2 - x.1} = m$

By plugging the values into this formula, we can solve for the slope.

-1 - 4 / -8 - 0

-5 / -8

Because there are two negatives, they cancel out;

The slope is 5/8

Answer:

$110

Step-by-step explanation:

Let a, b, and c represent the earnings of Alan, Bob, and Charles. The problem statement tells us ...

a + b + c = 480 . . . . . . the combined total of their earnings

-a + b = 40 . . . . . . . . . . Bob earned 40 more than Alan

2a - c = 0 . . . . . . . . . . . Charles earned twice as much as Alan

Adding the first and third equations, we get ...

(a + b + c) + (2a - c) = (480) + (0)

3a + b = 480

Subtracting the second equation gives ...

(3a +b) - (-a +b) = (480) -(40)

4a = 440 . . . . . . . . simplify

a = 110 . . . . . . . . . . divide by the coefficient of a

Alan earned $110.

_____

<em>Check</em>

Bob earned $40 more, so $150. Charles earned twice as much, so $220.

The total is then $110 +150 +220 = $480 . . . . as required
