For a given (but unknown) slope m, the standard equation is
y=mx+b
If the line passes through a point (x1,y1), the equation of the line is
(y-y1)=m(x-x1)
in the given question, (x1,y1)=(5,-3), so you can figure out the equation in terms of m.
You welcome to post your answer for a check.
Write an equation in standard form for the line whose slope is undefined that passes through (5,-3)
Please help me solve, my answer is 5x-3y=0... It was marked wrong and i can not seem to figure it out.

y=0-3 ? so simplified y=-3
Not really, for example, a line of slope m that passes through a point (7,6) would be written as:
(y-7)=m(x-6)
Expanding,
y-7 = mx -6m
transposing -7 to the right,
y=mx - 6m +7
would be a line of slope m passing through the point (7,6).
Now can you try to figure out a line with slope m that passes through (5,-3)?
(y-7)=m(x-6)
Expanding,
y-7 = mx -6m
transposing -7 to the right,
y=mx - 6m +7
would be a line of slope m passing through the point (7,6).
Now can you try to figure out a line with slope m that passes through (5,-3)?
