find the y-intercept of the function y=2x-8
To find the y-intercept of the function y = 2x - 8, we need to recall that the y-intercept occurs when x = 0.
To find the y-intercept, substitute x = 0 into the equation:
y = 2(0) - 8
Simplifying:
y = -8
Therefore, the y-intercept of the function y = 2x - 8 is -8.
