Answer is x intercept is 4

Step by step

The x-intercept is the point where the value of y=0. For this pair, the point is (4,0).
The y-intercept is the place where the value of x=0, for this pair the point is (0, 24)

To find the y and x-intercept, we need to find the line using the two points given.

First, let's find the slope, use the slope formula:


m=(y_(2-)y_1)/(x_2-x_1)

Replace the values:


m=(0-24)/(4-0)=(-24)/(4)=-6

Then, use the next formula to find the line:


y-y_1=m(x-x_1)

Use the point (0,24)


y-24=-6(x-0)
y-24=-6x

Solve the equation for y:

Add both sides 24


y-24+24=-6x+24
y\text{ = -6x+24}

Where -6 is the slope and 24 is the y-intercept.

Now, to find the x-intercept you need to set y=0.


0=-6x+24

Then, solve the equation for x:


6x\text{ = 24}
x=(24)/(6)=4

Therefore, the x-intercept is 4.
