Question

FAN AND MEDAL
i really need help especially with #3
1. Write the inequality for the graph?

A.
y ≥ –2x + 4

B.
y > –2x + 4

C.
y < –2x + 4*MY CHOICE*

D.
y ≤ –2x + 4

2. What are the x- and y-intercepts of the line: 2x – 3y = –12?

A.
x-intercept –4, y-intercept 6

B.
x-intercept 4, y-intercept –6

C.
x-intercept 6, y-intercept –4

D.
x-intercept –6, y-intercept 4

3.Write the equation of the graph?

A.
y – 3 = ½(x + 1)

B.
y + 3 = –½(x – 1)

C.
y – 3 = –½(x + 1)

D.
y = ½x + 5

Answer 1

I thought A or B For the first one..

Answer 2

@ClarissaMorgenstern hmmm... i dont think so because a dashed boundary line with shading below the boundary line uses the < symbol but i'm not sure

Answer 3

For the first one, your choice is correct. Plug in the point (0,0) into the inequality- you'll see it works.

Answer 4

For the second one, first rewrite the equation to isolate y.
2x – 3y = –12
-3y = -12 -2x
y = 4 +2/3x

Answer 5

Setting y to 0 gives us:
0 = 4 + 2/3x
x = 6

Answer 6

Setting x to 0 gives us :
y = 4 + 2/3(0)
y= 4

Answer 7

@greenglasses thank you

Answer 8

For the last one, the answer is D- it's the only one with a y-intercept of 5.

Answer 9

@greenglasses thanks i really do appreciate it
