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=1
b=-1
The slope of the line is the value of m, and the y-intercept is the value of b.
Slope: 1
y-intercept: -1
Slope: 1
y-intercept: -1
Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values.
