$y = \frac{3}{5} x + \frac{9}{5}$ $y=3/5x+9/5$

$3 x - 5 y = - 9$ $3x-5y=-9$

let's convert it to slope point form $y = m x + b$ $y=mx+b$

$3 x - 5 y = - 9$ $3x-5y=-9$

$- 5 y = - 3 x - 9$ $-5y=-3x-9$

$\frac{- 5 y}{- 5} = \frac{- 3 x - 9}{- 5}$ $(-5y)/-5=(-3x-9)/-5$

$y = \frac{3}{5} x + \frac{9}{5}$ $y=3/5x+9/5$

so the slope $m = \frac{3}{5}$ $m=3/5$ and the y-intercept $b = \frac{9}{5}$ $b=9/5$

graph{y=3/5x+9/5 [-11.875, 8.125, -3.4, 6.6]}
