What is an equation of the line that passes through the point (-3,-7) and is parallel to the line 3x−y=5?

Answer 1

solve for y

y=3x-5, in this form the coefficient of the x term is the slope = m = 3

y=mx+b is the general form of the equation with b=y intercept and m= slope

y=3x + b, with b calculated by plugging in the point

-7=3(-3) + b

b = -7+9 =2

y=3x+2 is the equation of the parallel line going through the point (-3,-7)
