Answer:y= 2x+7
Step-by-step explanation:
They are all pretty much want you to create the equation so the formula they want is y=mx+b format.
First problem(1,9) slope 2
Y=mx +b
Where y is 9,x is 1 and slope (m) is 2.
Now solve for b using equation
Y=mx +b
9= 2(1)+b
9=2+b
9-2=b
7=b
Now you can create equation
Y= 2x+7
Prob.4
(3,-6) and (-1,2)
First find slope
M= y2-y1/x2-x1
M= 2-(-6)/-1-3
M = 8/-4
M= -2
Your slope "m" is -2
Now do as problem 1 get one of the points and your slope to get equation .
(3,-6) slope -2
Y=mx+b
-6= -2(3)+b
-6= -6+b
-6+6=b
0=b
Y= -2x
Problem 7
(5,13) (10,14)
You solve this one as problem 4 same steps that I did above .
Problem 8 is also the same as steps in problem 4
( 2,160) and ( 2.75,220)
I hope this helps you
Answer:
90
Step-by-step explanation:
The mean is the average:
(92 + 96 + 94 + 88 + x) / 5 ≥ 92
370 + x ≥ 460
x ≥ 90
