Each line has one equation
[tex]y-y1=m(x-x1)[/tex]m is the slope of the line
(x1, x2) is a point on the line
We can find m by using this rule
[tex]m=\frac{y2-y1}{x2-x1}[/tex]From the graph the line passes through points (0, 4) and (3, 6)
(x1, y1) = (0, 4)
(x2, y2) = (3, 6)
Substitute them in the rule above to find m
[tex]m=\frac{6-4}{3-0}=\frac{2}{3}[/tex]Now let us put it in the form of the equation above
