x- and y-intercepts.

Question

3x – 8y = 8 y-intercept

Answer 1

The x-intercept is the point on the x-axis.  It has the point (x, 0).   Set y=0 into the equation.

 

3x - 8(0) = 8

3x = 8

 

x = 8/3

 

The x-intercept is  (8/3, 0).

 

 

The y-intercept is the point on the y-axis.  It has the point (0, y).   Set x=0 into the equation.

 

3(0) - 8y = 8

       - 8y = 8

           y = -1

 

The y-intercept is  (0, -1).

Answer 2

The y-intercept is at x = 0.

3(0) - 8y = 8

0 - 8y = 8

y = -1

 

y-intercept is (0, -1)
