Question

What is the y-intercept of a line represented by y = 7x - 15 ? 7 -7 15 -15

Answer 1

In the equation y = 7x - 15, the y-intercept is the value of y when x = 0. To find it, substitute x = 0 into the equation:

y = 7(0) - 15

y = -15

Therefore, the y-intercept of the line represented by y = 7x - 15 is -15.
