y<-13x+4

Combine x and 13.

y<-x3+4

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y=mx+b

Find the values of m and b using the form y=mx+b.

m=-13

b=4

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope: -13

y-intercept: 4

Slope: -13

y-intercept: 4

Graph a dashed line, then shade the area below the boundary line since y is less than -x3+4.

y<-x3+4
