Question

Last one which graph is right?

Answer 1

Question 21

`x+2y=-10 \\ \\ 2y=-x-10 \\ \\ y=-(1)/(2)x-5`.

• The slope is -1/2 (so the line is decreasing), and the y-intercept is -5, so the answer is D.

Question 22

`3x-y=-2 \\ \\ y-3x=2 \\ \\ y=3x+2`

• The slope is 3 (so the line is increasing), and the y-intercept is 2, so the answer is D.

Answer 2

21.) D

22.) A

Explanation:

22.) intercepts at -2 and has a slope of 3
