Math
y=3x-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=3
b=-5
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 3
y-intercept: -5
Slope: 3
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.
