Use the slope-intercept form to find the slope and y-intercept.
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=5
b=4
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 5
y-intercept: 4
Slope: 5
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.
Choose 0 to substitute in for x to find the ordered pair.
Replace the variable x with 0 in the expression.
f(0)=5(0)+4
Simplify the result.
Multiply 5 by 0.
f(0)=0+4
f(0)=4
4
