Yea! That's how you do it.
Now just multiply -5%2F6 with (4)
Then subtract that value on both sides and get the y-intercept, or "b".

y-%28-3%29%29=-%285%2F6%29%28x-4%29, using point-slope equation form


Let x=0 to find y-intercept.
y%2B3=-%285%2F6%29%280-4%29
y=-3-%285%2F6%29%28-4%29
y=-3%2B5%2A%282%2F3%29
y=10%2F3-3=10%2F3-9%2F3
y=1%2F3-------------y-intercept.
