3.5 – Write and Graph Equations of Lines
Linear equations may be written in different forms. The general form of a linear equation in slope-intercept form y = mx+b, where m
is the slope and b is the y-intercept.
3.5 – Write and Graph Equations of Lines
Example 1:
Write an equation of the line in slope-intercept form.
