Help me please I’ll give a lot of points

21. B

22. D

23. C

24. y = 3x - 12

Step-by-step explanation:

21.  it has to be a positive slope since the graph shows it is increasing/positive slope. Has to be A or B. But it isn't A because where x = 1 1/2, y doesn't equal 0 like the graph shows.

22. It is D if you rewrite the equation starting with y=, so you subtract 2x on both sides to get y = -2x +6. Parallel means slopes are the same, so the slope has to be -2, which is D.

23. The only one that fits the description is C.

24.

in standard form, rearrange the equation so only y is on one side, the rest on the other.

-4x + 2y  = 2x - 24

first add 4x on both sides so -4x cancels out on the left hand side.

-4x + 4x + 2y  = 2x + 4x - 24

simplify it and get 2y = 6x - 24

divide both side by 2

y = 3x - 12

plot this as shown with arrows on lines.

please give thanks :)

i'm assuming it's looking for the missing length, which should be 4cm

hope this !

72 is the answer to this problem
