Question

The x and y intercepts of the line -4x + 9y = 72 are:​

Answer 1

Answer:

X intercept is - 18 and y intercept is 8

Answer 2

Answer:

The x and y-intercepts of line -4x + 9y = 72 are x = -18 and y = 8

Step-by-step explanation:

• There are mainly two types of intercepts

1. x-intercept
2. y-intercept

• The x-intercept is the point where the line cuts the x-axis. At this point y = 0.
• The y-intercept is the point where the line cuts the y-axis. At this point x = 0.
• Here in the given equation of the line ( - 4x + 9y = 72), we need to find its x and y-intercepts which means we need to find the point where the line cuts the x and y-axis.

Step 1:

For x-intercept take y=0

We get

-4x + 9 (0)=72

-4x = 72

x = -18

Step 2:

For y-intercept take x=0

We get

-4(0) + 9y=72

9y = 72

y = 8

Therefore the x and y-intercept come out to be -18 and 8 respectively
