# Graph y=7-5x y=7-5x
Reorder 7 and -5x.
y=-5x+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=-5
b=7
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: -5
y-intercept: 7
Slope: -5
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 1 to substitute in for x to find the ordered pair.
Replace the variable x with 1 in the expression.
f(1)=-5⋅1+7
Simplify the result.
Multiply -5 by 1.
f(1)=-5+7
Add -5 and 7.
f(1)=2
The final answer is 2.
2
2
The y value at x=1 is 2.
y=2
y=2
Choose 2 to substitute in for x to find the ordered pair.
Replace the variable x with 2 in the expression.
f(2)=-5⋅2+7
Simplify the result.
Multiply -5 by 2.
f(2)=-10+7
Add -10 and 7.
f(2)=-3
The final answer is -3.
-3
-3
The y value at x=2 is -3.
y=-3
y=-3
Create a table of the x and y values.
