Chapter 2: Q23. (page 101)

Find the x-intercept and the y-intercept of the graph of each equation. Then graph the equation.

-15y=x+4

Short Answer

Expert verified

The x-intercept is -4.

The y-intercept is 215.

Step by step solution

01

– Defining the x-intercept and y-intercept

The x-intercept is the value of x when y=0.

The y-intercept is the value of y when x=0.

02

– Determining the x-intercept

We have:

-15y=x+4

Putting y=0:

鈭�150=x+40=x+4x=鈭�4

Hence, x-intercept is -4.

03

– Determining the y-intercept

We have:

-15y=x+4

Putting x=0:

鈭�15y=0+4y=15+4y=215

Hence, y-intercept is 215.
