# Graph y=9/5x-1 y=95x-1
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=95
b=-1
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 95
y-intercept: -1
Slope: 95
y-intercept: -1
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)=9(0)5-1
Simplify the result.
Multiply 9 by 0.
f(0)=05-1
Divide 0 by 5.
f(0)=0-1
Subtract 1 from 0.
f(0)=-1
-1
-1
The y value at x=0 is -1.
y=-1
y=-1
Choose 1 to substitute in for x to find the ordered pair.
Replace the variable x with 1 in the expression.
f(1)=9(1)5-1
Simplify the result.
Multiply 9 by 1.
f(1)=95-1
To write -1 as a fraction with a common denominator, multiply by 55.
f(1)=95-1⋅55
Combine -1 and 55.
f(1)=95+-1⋅55
Combine the numerators over the common denominator.
f(1)=9-1⋅55
Simplify the numerator.
Multiply -1 by 5.
f(1)=9-55
Subtract 5 from 9.
f(1)=45
f(1)=45
45
45
The y value at x=1 is 45.
y=45
y=45
Create a table of the x and y values.
