Arectangular prism has a volume of 120 cm3. its length is 5 cm and its width is 8 cm. what is the prism’s height?
15 cm
24 cm
40 cm
3 cm

V = w h l
120 = 8 h 5
120 = 40 h
3 = h

Checking it:
120 = 8 x 5 x 3
It works! The last option is the correct one.

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
