What is the (y)-intercept of the line (y=8)?
Answer and explanation
Correct answer: 8
The line y=8 is a horizontal line, so the value of y remains 8 for every value of x. To find the y-intercept, put x=0; the point obtained is (0, 8). Hence, the y-intercept is 8. It would be -8 only for the equation y=-8. Exam tip: for a line of the form y=c, the y-intercept is always c.
