Answer:
Step-by-step explanation:in standard form y= ax+b
-4y = -3x+28
4y =3x-28
or y= 3/4 x -7
So a= 3/4 = slope and -7 is y intercept ( parallel lines have same slope)
Equation 3 is
y= 3/4x-2
which also has slope = 3/4 and y intercept = -2
Parallel lines have same slope
Similarly a perpendicular line will have slope of - 1/a
For equation
y= ax+b
Perpendicular line is
y=( -1/a) x +c
