Determine the x and y intercept

Question

1.) 2y= - 16

2.) - 3x = 9

3.) y=x+2

Answer 1

For each of the questions above, the x-intercept is found by setting y = 0 and solving for x; whereas the y-intercept is found by setting x = 0, and solving for y. I will show an example below:

---------------------------------

Example: 3x + 4y = 12

---------------------------------

Finding x-intercept:

Let us set y = 0 in the equation above.

3x+4*0=12

3x = 12

x = 12/3

x = 4

----------------------------------

Finding the y-intercept:

Let us set x = 0.

3*0 + 4y = 12

4y =12

y = 12/4

y = 3
