Answer 1

\[\huge\rm y-y_1=m(x-x_1)\] ` point slope ` form
where m is slope and (x_1 ,y_1) is a point where line passes through
so just plugin the numbers :=))

Answer 2

what about this one?

Answer 3

first rewrite the given equation in slope intercept form y=mx+b
Parallel lines have the same slope
if slope of line A is `4` then slope of parallel will be 4
perpendicular slopes are `negative reciprocal`
if slope of line A is a/b then slope of perpendicular line would be negative b/a (flip the fraction and change the sign )
