Math
(0,8) , (4,16)
Find the value of the slope.
Tap for more steps…
Slope is equal to the change in y over the change in x, or rise over run.
m=change in ychange in x
The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
m=y2-y1x2-x1
Substitute in the values of x and y into the equation to find the slope.
m=16-(8)4-(0)

Multiply -1 by 0.
m=84+0
Add 4 and 0.
m=84
m=84
Divide 8 by 4.
m=2
m=2
m=2
Find the value of the y-intercept.
Tap for more steps…
Substitute the value of m into the slope-intercept form of the equation, y=mx+b.
y=(2)⋅x+b
Substitute the value of x into the slope-intercept form of the equation, y=mx+b.
y=(2)⋅(0)+b
Substitute the value of y into the slope-intercept form of the equation, y=mx+b.
8=(2)⋅(0)+b
Rewrite the equation as (2)⋅(0)+b=8.
(2)⋅(0)+b=8
Simplify (2)⋅(0)+b.
Tap for more steps…
Multiply 2 by 0.
0+b=8
Add 0 and b.
b=8
b=8
b=8
The values of the slope and y-intercept are m=2 and b=8.
m=2
b=8
