Question

Write the equation of a line parallel to the line y = 2x that passes through -2,-1

Answer 1

Y=2x+3. Sorry if I’m incorrect

Answer 2

y = 2x + 3

Explanation:

A line parallel to y = 2x has exactly the same slope but a different y-intercept, b.

Start with y = mx + b, and replace m with 2, y with -1 and x with -2:

-1 = 2(-2) + b, or

-1 = -4 + b.

Then b = 3, and the desired equation is y = 2x + 3
