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=2
b=34
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 2
y-intercept: 34
Slope: 2

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)=2(0)+34
Simplify the result.
Multiply 2 by 0.
f(0)=0+34
f(0)=34

The y value at x=0 is 34.
y=34
y=34
Choose 1 to substitute in for x to find the ordered pair.
Replace the variable x with 1 in the expression.
f(1)=2(1)+34
Simplify the result.
Multiply 2 by 1.
f(1)=2+34
To write 2 as a fraction with a common denominator, multiply by 44.
f(1)=2⋅44+34
Combine 2 and 44.
f(1)=2⋅44+34
Combine the numerators over the common denominator.
f(1)=2⋅4+34
Simplify the numerator.
Multiply 2 by 4.
f(1)=8+34
f(1)=114
f(1)=114
