Slope $= 1$ $=1$

You can solve this by inspection
from the given $(- 3, - 3)$ $(-3, -3)$ and $(0, 0)$ $(0, 0)$

both points indicate $y = x$ $y=x$

that is $- 3 = - 3$ $-3=-3$ and $0 = 0$ $0=0$

therefore the equation is $y = x$ $y=x$

and using $y = m x + b$ $y=mx+b$ ,

$y = 1 \cdot x + 0$ $y=1*x+0$

we have $b = 0$ $b=0$ and $m = 1$ $m=1$

therefore slope $m = 1$ $m=1$
