Let's add 1 to each side to isolate y...
The equation is now in the form of slope-intercept.
b=y-intercept, the value of y when x=0.
Or we can take the point-slope equation and do something else...
Let's separate the constant from the variables...
Let's add 4x to both sides...
Let's add 1 to both sides...
The equation is now in the form of standard formula.
Because A=4, it is greater than zero. We have no additional work to do.
