Time-and-a-half doesn't make enough sense to answer the question. If you fix it, or comment below the correction I will gladly help.
Answer:
Step-by-step explanation:
slope-intercept form: y = mx + b
y = (x , y)
x = (x , y)
m = slope = 1/2
b = y-intercept = 89
Plug in the corresponding numbers & variables to the corresponding variables:
y = (1/2)x + 89
is your answer.

A line parallel to the y-axis that passes through (77,88) is x = 77. There is no slope-intercept form of this equation if our coordinate system is based upon a horizontal x-axis and a vertical y-axis.
i believe it’s D because where you have 20 marked it’s 20 more from where you are which would be around 40 which is why i’m saying D
