Find the slope of the line. On a coordinate plane, a line goes through (0, negative 2) and (2, negative 4). a. -1 c. -2 b. 2 d.
Sedbober [7]

Answer: Choice A) Slope = -1

==============================================

Explanation:

The two points given to us are (x1,y1) = (0,-2) and (x2,y2) = (2,-4)

Subtract the y coordinates

y2-y1 = -4-(-2) = -4+2 = -2

Subtract the x coordinates in the same order

x2-x1 = 2-0 = 2

Divide the two results to get the slope m

m = (y2-y1)/(x2-x1)

m = -2/2

m = -1

Yanka [14]

Answer:

42

Step-by-step explanation:

3 x {[(12-8) x 2] + [(11 - 9) x 3]}

12-8=4 and 11-9=2.

3 x ((4 x 2) + (2 x 3))

4 x 2= 8 and 2 x 3=6.

3 x (8 + 6)

8 + 6 is 14.

3 x 14 is 42.
