What would the x-intercept be?

Question

3x+4y=12

Thanks!

Answer 1

For the x intercept let y be equal to zero

 

We get

 

3x + 4 (0) = 12

 

3x = 12

 

x. = 4

 

So our x intercept would be (4,0)

Answer 2

To find the x-intercept, set y equal to zero and solve for x.  This is because the x-intercept is the point on the x-axis.

 

3x + 4(0) = 12

 

3x = 12

 

  x = 4

 

 

The x-intercept is (4, 0).
