# Graph r=3xs-8xt

r=3xs-8xt
Rewrite in slope-intercept form.
The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
y=mx+b
Simplify 3xs-8xt.
Move x.
r=3sx-8xt
Move x.
r=3sx-8tx
r=3sx-8tx
r=3sx-8tx
Use the slope-intercept form to find the slope and y-intercept.
Find the values of m and b using the form y=mx+b.
m=3
b=-8tx
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 3
y-intercept: -8tx
Slope: 3
y-intercept: -8tx
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)=3s(0)-8t⋅0
Simplify the result.
Simplify each term.
Multiply 3s(0).
Multiply 0 by 3.
f(0)=0s-8t⋅0
Multiply 0 by s.
f(0)=0-8t⋅0
f(0)=0-8t⋅0
Multiply -8t⋅0.
Multiply 0 by -8.
f(0)=0+0t
Multiply 0 by t.
f(0)=0+0
f(0)=0+0
f(0)=0+0
f(0)=0
