Question

The ordered pair below is a solution to which equation? (40, 5)
A. y = 8x
B. y = 5x
C. y = 1/8x
D. y = 1/5x

Answer 1

C
Plug in 40 for the x value. So you have 1/8 * 40/1 = 40/8

\[40\div8= 5\]

Answer 2

Find the equation of the line .

Answer 3

Find the slope by dividing the raise over the run.

m= (12-4)/(3-1) = 4

Take one of the points and plug into the slope intercept form y= mx + b

For point (1,4) you get 4 = 4(1) + b

So b = 0

So the equation of the line is y = 4x + 0
