## Solutions: Write Equations Using $$y=mx+b$$

Note the answers for 1, 2, and 3 were given on the previous page.

Given the points $$( -2, -1)$$ and $$(3, 2)$$.

$slope=\frac{2-(-1)}{-3-(-2)}=\frac{2+1}{3+2}=\frac{3}{5}$

$y=mx+b$

$2=\frac{3}{5}(3)+b$

$2=\frac{9}{5}+b$

$2-\frac{9}{5}=b$

$\frac{10}{5}-\frac{9}{5}=b$

$b=\frac{1}{5}$

Therefore the equation of the line is: $$y=\frac{3}{5}x+\frac{1}{5}$$.
