Question

The x and y intercepts of the line _4x+9y=72 are

Answer 1

Answer:

Step-by-step explanation:

Coordinates of the x-intercept are (x, 0)

Coordinates of the y-intercept are (0,y)

~~~~~~~~~

4x + 9y = 72

4(0) + 9y = 72 ⇒ y = 8

4x + 9(0) = 72 ⇒ x = 18

The x-intercept of the line is 18.

The y-intercept of the line is 8.

Answer 2

x intercept is 18  and y intercept is 8 in  4x + 9y = 72

Given:

Line 4x + 9y = 72

To Find:

x and  y intercept

Solution:

Intercept form of line

x/a + y/b  =  1

where a is x intercept and b is  intercept

4x + 9y = 72

Divide both side y 72

x/18  + y/8  = 1

x intercept is 18  and y intercept is 8

Another method

4x + 9y = 72

substitute y = 0 to get x intercept  

4x + 0 = 72

=> x  = 18

substitute x = 0 to get x intercept  

0x + 9y = 72

=> y  = 8

x intercept is 18  and y intercept is 8
