The y-intercept of a function is the value of y when x = 0.
To find the y-intercept, substitute x = 0 into the equation:
y = 2(0) - 6
y = -6
Therefore, the y-intercept of the function y = 2x - 6 is -6.
The equation of a function is y=2x−6 . If this function were graphed, what would its y -intercept be?
