The given equation has three variables. Your given point, F, will give values to the variables x and y, leaving only the variable c as unknown. You would then just solve for c and simplify.
A clear method which you can choose, is solve for c FIRST. Substitute the values from F into the formula for c and evaluate.
Performing that described method:
. Point F on the line is given as (4,-6).
Solving for c,
Substituting with point F,
The equation in the two variables x and y, is
Drawing the graph is just a matter of indicating the y-intercept, which is c in your equation, and using the slope, .
Note, knowing the given point F, you can also graph the line by indicating (4,-6) on the cartesian plane and using the slope, . In this way, if you make your axes suitably, you can read the y-intercept directly from the graphed line.
