Answer:
16)
17) y = -x - 4
18) y = -2x - 1
19) y = -2x
20)
Step-by-step explanation:
With the two points you find the slope using
Then using that slope, plug the slope in with one of the points values of x and y into the point slope formula, and smiplify that into the y-intercept formula.
a. To get a B grade the least average is 80. That is a total of 5*80 = 400.
So if the least score is x we have;
84 + 95 + 83 + 86 + x ≥ 400
x ≥ 400 - 348
x ≥ 52
so the least score is 52
Answer:
40
