Answer 1

A) Slope =

`m = (1)/(4) x`

explanation:

Take 2 random points off the line, I used (4,1) & (8,2)

The formula to find the slope when given 2 points is

`m = (rise)/(run) = (y2 - y1)/(x2 - x1)`

so in this case x1 & y1 are assigned to (4,1)

• 4 = x1
• 1 = y1

and x2 & y2 are assigned to (8,2)

• 8 = x2
• 2 = y2

so substitute the numbers into the formula and solve !

`m= (y2 - y1)/(x2 - x1) = (2 - 1)/(8 - 4) = (1)/(4)`

this will result in the answer I got above!!

B) yes it does show a constant rate of change cause it's increasing in 1/4x intervals

C) just because you move the placement of a line on the graph doesn't mean it's going to effect the slope as long as the numbers on the axis don't change!!
