How do you find the x and y intercept given #y=3x-6#?
1 Answer
Plug in
Explanation:
To find the x-intercept, that is, where the line touches the x-axis, the y-value is equal to
You get:
Now, you must solve for
Add
Divide both sides by
Knowing that
We use the same logic to find the y-intercept, at which we know that
You get:
Multiply:
Subtract:
Therefore, the y-intercept is
Another way to find the y-intercept is to recognize that
