The answer is D. you know that the equation must end in +4 as the yintercept is at four (y=4 when x=0)
then you can work out that it is 3x because when x changes by -4, y changes by -12, which is three times as much.
Hope this makes sense!

Slope = (-8 - 4)/(-4 -0) = -12/-4 = 3

y-intercept so b = 4

equation: y = 3x + 4

answer: <span>C. y = 3x + 4</span>

Illusion [34]

Answer:

Option A, Shannon paid $ 7 per hour to labor than Joni

Step-by-step explanation:

Total amount paid by Shannon = $339.50

Total cost of 3.5 hours of labor paid by Shannon =($339.50- $112)

Total cost of 3.5 hours of labor paid by Shannon = $227.5/3.5

Total cost of 1 hours of labor paid by Shannon  $65 per hour

Total amount paid by Joni = $455

Total cost of 2.5 hours of labor paid by Joni =  $455- $$310

Total cost of 1 hours of labor paid by Joni = $145/2.5

Total cost of 1 hours of labor paid by Joni = $ 58

Hence, Shannon paid $ 7 per hour to labor than Joni

Option A is correct
