# Graph y=3x+11 y=3x+11
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=3
b=11
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 3
y-intercept: 11
Slope: 3
y-intercept: 11
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)=3(0)+11
Simplify the result.
Multiply 3 by 0.
f(0)=0+11
f(0)=11
11
11
The y value at x=0 is 11.
y=11
y=11
Choose 1 to substitute in for x to find the ordered pair.
Replace the variable x with 1 in the expression.
f(1)=3(1)+11
Simplify the result.
Multiply 3 by 1.
f(1)=3+11
f(1)=14
14
14
The y value at x=1 is 14.
y=14
y=14
Create a table of the x and y values.
