Answer:
a) 8x
b) 40
c) 55% - 60%d) the y Intercept means that you would get a min of a 40% if you don't study for the quiz.
Step-by-step explanation:
Ok, So in the equation [tex]y = 8x + 40[/tex], you break it down. The [tex]8x[/tex] Represents the slope. Since it is not a fraction, you go up 8 units and over 1 unit. Now, the [tex]+40[/tex] represents the y-Intercept or it is [tex](0, 40)[/tex] on the graph. Now for C you just look at the y for the lowest and highest score for this and just put it as between X - Y. For D, you just take the y and look at it with the x as the y is your test scores. So with the y intercept being [tex](0, 40)[/tex] it means that since 40% is at the 0 point, it is the lowest "possible" score you can get. But that's not really the case.
