Answer:
The midrange of the data set shown is 85
Answer:
not quite sure the specifc answer of this question at this time
Step-by-step explanation:
I think the answer is x times 2 - 61
-3/4x + 5/6 y = 15
Multiply through by 6
-9/2x + 5y = 90
Add 9/2x to both sides
5y = 90 + 9/2x
Divide both sides by 5
y = 18 + 9/10x
y = 9/10x + 18
Comparing with the general equation of a straight line y = mx + c
Gradient (m) = 9/10 or 0.9
and the y - intercept (c) = 18
