Darius designed a billboard. The billboard is 144 inches wide by 480 inches high. Darius uses a computer to design the billboard. Determine the unknown dimension to find the area of the computer design. 12 inches x ? inches.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
