# Graph y=-1/7x+2 y=-17x+2
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=-17
b=2
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: -17
y-intercept: 2
Slope: -17
y-intercept: 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)=-07+2
Simplify the result.
Simplify each term.
Divide 0 by 7.
f(0)=-0+2
Multiply -1 by 0.
f(0)=0+2
f(0)=0+2
f(0)=2

Choose 1 to substitute in for x to find the ordered pair.
Replace the variable x with 1 in the expression.
f(1)=-17+2
Simplify the result.
To write 2 as a fraction with a common denominator, multiply by 77.
f(1)=-17+2⋅77
Combine 2 and 77.
f(1)=-17+2⋅77
Combine the numerators over the common denominator.
f(1)=-1+2⋅77
Simplify the numerator.
Multiply 2 by 7.
f(1)=-1+147
f(1)=137
f(1)=137
