# Graph 13x-19

13x-19
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=13
b=-19
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 13
y-intercept: -19
Slope: 13
y-intercept: -19
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 1 to substitute in for x to find the ordered pair.
Replace the variable x with 1 in the expression.
f(1)=13(1)-19
Simplify the result.
Multiply 13 by 1.
f(1)=13-19
Subtract 19 from 13.
f(1)=-6
-6
-6
The y value at x=1 is -6.
y=-6
y=-6
Choose 2 to substitute in for x to find the ordered pair.
Replace the variable x with 2 in the expression.
f(2)=13(2)-19
Simplify the result.
Multiply 13 by 2.
f(2)=26-19
Subtract 19 from 26.
f(2)=7
7
7
The y value at x=2 is 7.
y=7
y=7
Create a table of the x and y values.
