Question

What is the equation of a line parallel to y = x+2
and passes through (1, 2)?

Answer 1

Answer: y - x = 1

Step-by-step explanation: Note : for two lines to be parallel, then they have the same slope.

i.e the slope is 1

Using y - y1 = m ( x-x1) to find the equation of the line

⇒ y - 2 = 1 (x - 1)

y - 2 = x - 1

y - x = -1 +2

y - x = 1

it could also be written in slope intercept form as y = x + 1
