Answer:
y = 4.125x + 496.25
Step-by-step explanation:
Set the data up as points. Then deal with the points.
Givens
(30,620)
(70,785)
y2 = 785
y1 = 620
x2 = 70
x1 = 30
Formula
Slope = (y2 - y1) / (x2 - x1)
Solution
Slope = (785 - 620)/(70 - 30)
Slope = 165 / 40
Slope = 4.125
===================
Now you need the y intercept. Either one of the two given points will give you that.
y = 620
x = 30
m = 4.125
y = mx + b
620 = 4.125*30 + b
620 = 123.75 + b
620 - 123.75 + b
b = 496.25
The answer to that would be 0 because the line goes through the orgin witch the points are 0
Answer:
B) 2
C) y = 2x
Step-by-step explanation:
Part B
Constant is 2 because in order to get x to the value of y, you must multiply by 2.
Part C
y = 2x
Answer:
c
Step-by-step explanation:
All answers are the same, 9, but only the first choice follows a correct simplification.
