First we need equations for Slope Intercept form and Point Slope form.
Point Slope: y-y₁=m(x-x₁)
Slope Intercept: y=mx+b
So with m= 2/3 and coordinate point of (-3,-1) we will plugin to the point slope. Then once we plugin we must take the point slope and convert it into slope intercept form by distributing and adding/subtracting/multiplying/dividing where needed.

Sure.
So where see "m" you plugin 2/3 for your slope. Where you see your x (which is -3) you plugin the -3, and same for y (which is -1). You plugin these numbers to your point slope equation.
Right after you filled out your equation you will now distribute your m into the (x - x sub 1) part. So it should look like this y+1=2/3x - 2
You then will subtract over the one and get your slope intercept form equation of y = 2/3x - 3
Where the 2/3 = your slop
and your -3 = the y-intercept
Hope I could help!
