Answer:
Step-by-step explanation:
y=mx+b is the formula.
m is the slope and b is the y-intercept.
y-intercept is when x is 0 and x-intercept is when y is 0. So if x is 0, y=m(0)+b which is y=b. So on the graph y will be b when x is 0.
So in y=7x+2, 7 is the slope and 2 is the y-intercept.
Answer:
a. 80.25
b. 104
Step-by-step explanation:
For (a), you add all the numbers together and divide by 4 because there are 4 test scores.
87 + 92 + 63 + 79 ÷ 5 = 80.25
For (b), we need to set up an equation. It is going to be a similar concept.
87 + 92 + 63 + 79 + x ÷ 5 = 85
x = 104
Hope this helps!
