You are 9 miles away from home. you start biking home at a speed of 6 miles per hour.
a. write an equation. in standard form that represents your distance from home y after x hours.
b. find the y-intercept of the graph. what does this represent?
c. find the x-intercept of the graph. what does this represent?

The distance and speed are illustrations of linear equations

The given parameters are:

(a) The standard equation

Because the distance reduces with time, the equation is:

This gives

Add 6x to both sides

(b) The y-intercept

This is the initial distance away from home.

So, the y-intercept is 9

(c) The x-intercept

Set y to 0, to calculate the x-intercept

Divide both sides by 6

This is the initial time away from home.

So, the x-intercept is 1.5

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
