Question

What is the equation of a line that contains the point (2,1) and is parallel to the line: y = 3x – 4?

Answer 1

Hello:
an equation for the line is : y =mx +b (m: is a slope )

parallel to the line or the form y = 3x- 4 ( same slope m = 3)
the equation is : y = 3x+b

through the point (2,1) : 1 =3(2)+b....... b=-5
the equation is : y = 3x -5
