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.

3.5 – Write and Graph Equations of Lines Example 2: Write an equation of the line in slope- intercept form.

Can solve in either of two ways: OR Plug in m, x, and y Solve for b. Then, plug back into the equation m and b. Solution:
