The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
y=mx+b
Reorder 4 and -x2.
y<-x2+4
Rewrite in slope-intercept form.
y=-12x+4
y=-12x+4
Use the slope-intercept form to find the slope and y-intercept.
Tap for more steps…
Find the values of m and b using the form y=mx+b.
m=-12
b=4
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: -12
y-intercept: 4
Slope: -12
y-intercept: 4
Slope: -12
y-intercept: 4
Graph a dashed line, then shade the area below the boundary line since y is less than 4-x2.
y<4-x2
