Question

Plz Help I need to get these right and im already grounded so Help a brotha out

Answer 1

1). Correct answer is D

2). Correct answer is A

Explanation:

1).

For the points given, (-1, -1) and (2, -2), we have to find the slope.

Slope formula is (y2 - y1) / (x2 - x1), or rise over run.

Simply fill in the formula and you will get:

y2 = -2

x2 = 2

y1 = -1

x1 = -1

OR

(-2 - (-1)) / (2 - (-1)) which is D

2).

For the two points given, (2, 0) and (0, -3), find the slope.

Using the same equation above, (y2 - y1) / (x2 - x1), or rise over run, fill it in and solve and you will get your answer.

y2 = 0

x2 = 2

y1 = -3

x1 = 0

(0 - (-3)) / (2 - 0) = 3/2 which is A

Answer 2

Explanation:

Graph A:

D ((y2-y1)/(x2-x1) or (y1-y2)(x1-x2))

Graph B:

A (same as above or simply take the rise divided by the run)
