Slope-intercept form is y = mx + b.
In this form, m is slope and b is y-intercept.
Slope is rise over run. The formula for this is (y2-y1)/(x2-x1).
Y-intercept is the value of y when x is equal to 0.
1. Slope = 8 ; Y-intercept = 0
y = mx + b
m = 8 ; b = 0
y = 8x + 0
y = 8x
2. Slope = 1 ; Y-intercept = 2
y = mx + b
m = 1 ; b = 2
y = 1x + 2
y = x + 2
The answer to #1 is y = 8x.
The answer to #2 is y = x + 2.

The height of the cylinder is 6 cm.
If the volume of the cylinder is 54π cm³, and we know the radius, we can use the formula for the volume of a cylinder to figure out the length of the height.
V = πr²h
Substitute
54π = 9h<span>π
</span>
Divide each side by <span>π
54 = 9h
Get h by itself
h = 6, which means that the height of the cylinder is 6 cm. </span>
The answer would be 65. a
