Answer:
Equation in point slope form is: 
Solving for y we get: 
Step-by-step explanation:
We are given:
Slope = 4
Point (-6,-3)
Point Slope form:
We need to write equation for point-slope form
The general equation of point slope form is: 
Where m is slope and
are points on the line
Now putting values of slope m= 4,
and finding equation

So, equation in point slope form is: 
Solve for y

So, solving for y we get: 
Learn this...it really helps...
HOY -- horizontal line, 0 slope, represented by y = a number
VUX -- vertical line, undefined slope, represented by x = a number
y = 3....this is a horizontal line with a slope of 0
