Answer:
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 :)
