Answer:
C
Step-by-step explanation:
The y-intercept is at x=0, y=3.
Answer:
x = -2 and y = 1
Step-by-step explanation:

<span>Plan 1: $50 for a monthly pass and a $3 fee for each gym visit
So, the monthly pass is 50 plus 3 for each visit. You know 50 stays constant no matter how much Hayley goes to the gym so you can already put that into the form as 'b' also known as the y-intercept.
y=mx+50
Now, you need to find the slope which is the amount it increases or decreases by every time. Since Hayley gets charged $3 every visit, that would be the slope (m).
Plan 1: y=3x+50

Plan 2: $10 for each gym visit

There is only a slope (m) for this. Technically there is a y-intercept (b), but since that is 0 it is not needed. Plug in the values.
y=mx+b
y=10x
You have to divide 128 by 8 and you will get 16. So the answer is 16
The third one since you can interpret the first column of the graph as the x coordinates and the second column as the y coordinate.
