# Graph y=-5/3x+5 y=-53x+5
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=-53
b=5
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: -53
y-intercept: 5
Slope: -53
y-intercept: 5
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 3 to substitute in for x to find the ordered pair.
Replace the variable x with 3 in the expression.
f(3)=-5(3)3+5
