2019-03-13 5:48 pm
A wooden access ramp is being built to reach a platform that sits 30 inches above the floor. The ramp drops 2 inches for every 25-inch run. Write a linear equation that relates the height y of the ramp above the floor to the horizontal distance x from the platform.

✔ 最佳答案
x = 0, y = 30x = 25, y = 28
y - 30 = (28-30)(x-0)/(25-0) : 2 point form
y = 30 - 2x/25 : slope intercept form
2x/25 + y = 30
In standard form, the linear equation is:
2x + 25y = 750

Height of the ramp in inches = (30 inches) - (2 inches) * (Horizontal distance from the platform in inches)/(25 inch)
Height of the ramp in inches = (30 inches) - 0.08 * (Horizontal distance from the platform in inches)
The equation is: y = 30 - 0.08x
Height of the ramp in inches = (30 inches) - 0.08 * (Horizontal distance from the platform in inches)
The equation is: y = 30 - 0.08x

y = 30 - 2x/25
