Answer:
40 * 6.5 = 260 --> D. 260.00
The answer is 4.85, rounded
To find the slope of a line, we can use the following formula:

m-term stands for slope or gradient. The formula is useful whenever you want to find a slope of two points.
Let these be the following:

Substitute the points in formula:

Negative multiply negative always come out as positive.

Since m stands for slope, we can say that:

(x - 4)(x + 3) = x^2 + 3x - 4x - 12 = x^2 - x - 12
