To find the slope and y-intercept for the equation y = 15x - 100, we can apply the knowledge that the slope is the coefficient of x, and the y-intercept is the value of y when x=0.
In this equation, the coefficient of x is 15. Therefore, the slope is 15.
To determine the y-intercept, we need to find the value of y when x=0.
Substituting x=0 into the equation, we get:
y = 15(0) - 100
y = -100
Hence, the y-intercept is -100.
Therefore, the slope of the equation y = 15x - 100 is 15, and the y-intercept is -100.
