Brainliest + Points!<br><br> Please explain !
Morgarella [4.7K]

Answer:

A) -2/5

Step-by-step explanation:

Note that for a slope, the slope of the line is found by using the equation:

slope = (rise/run).

In this case, find two points. For example, i will use:

(0, 2) & (5, 0). (x = 0, y = 2) ; (x = 5, y = 0)

Note that "rise" = y, and "run" = x. Plug in the corresponding numbers for the corresponding points.

(2 - 0)/(0 - 5) = slope

Simplify

(2)/(-5) = slope

-(2/5) is your answer.

Note that it does not matter where the negative sign is placed.
