Answer 1

C.
`(4)/(5)`

Explanation:

In order to find the slope knowing two points, use the slope formula
`(y_2 - y_1)/(x_2-x_1)`.
`x_1` and
`y_1` represent the x and y values of one point the line intersects, and
`x_2` and
`y_2` represent the x and y values of another point the line intersects.

Knowing this, use the points (-4, -4) and (6, 4) for the formula. Substitute -4 for
`x_1`, -4 for
`y_1`, 6 for
`x_2`, and 4 for
`y_2`. Then, simplify:

`((4) - (-4))/((6) - (-4)) \\= (4+4)/(6+4) \\= (8)/(10) \\= (4)/(5)`

Thus,
`(4)/(5)` is the slope of the line.
