Answer
Y-intercept: (0,4)
Slope: -1
Work Step by Step
The equation is in slope intercept form, which is the form $y=mx+b$. In this equation, the slope is m, and the y-intercept is b. Thus, we see that the slope of the given function is -1, and the y-intercept is 4.
If we were to want to graph this equation, we would first start by making a point at the y-intercept. Then, we would draw the line through that point that has the given slope.
