4x + 3y = 12 and 4x + 3y = 3 are parallel lines
Let us first find the distance between the parallel lines
3×4−342+32√=95=1.8
Let A be the angle made by the line with 4x + 3y = 3
tan A=32−1.82√1.8=43
Let m be the slope of the line
tan A=m−431+4m3=43⇒9m−12=12 + 16m⇒m=−247
Equation of the line:
y−(−7)=−247(x−(−2))
7y + 24x + 97=0
