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=53
b=-4
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 53
y-intercept: -4
Slope: 53
y-intercept: -4
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.

Replace the variable x with 0 in the expression.
f(0)=5(0)3-4
Simplify the result.
Tap for more steps…
Multiply 5 by 0.
f(0)=03-4
Divide 0 by 3.
f(0)=0-4
Subtract 4 from 0.
f(0)=-4
The final answer is -4.
