# Graph y=-1/2x+7 y=-12x+7
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=-12
b=7
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: -12
y-intercept: 7
Slope: -12
y-intercept: 7
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 2 to substitute in for x to find the ordered pair.
Replace the variable x with 2 in the expression.
f(2)=-22+7
Simplify the result.
Simplify each term.
Divide 2 by 2.
f(2)=-1⋅1+7
Multiply -1 by 1.
f(2)=-1+7
f(2)=-1+7
f(2)=6

Choose 0 to substitute in for x to find the ordered pair.
Replace the variable x with 0 in the expression.
f(0)=-02+7
Simplify the result.
Simplify each term.
Divide 0 by 2.
f(0)=-0+7
Multiply -1 by 0.
f(0)=0+7
f(0)=0+7
