Explanation:
Well, if you're trying to find the x-intercept, you should look where the line crosses the x-axis. If the line crosses at 6, then the x-intercept is 6. So what I'm saying is the answer is 6.
Btw, if you're trying to find the y-intercept, just look where the line crosses the y-axis, (vertical axis) and then that's your answer.
Example: If there is a line crossing through a 5 on the y-axis, that is your y-intercept.
Example: If there is a line crossing through a 5 on the x-axis, that is your x-intercept.
I hope this answers your question.
