Question

The equation of a line is y = 2x + 3. What is the equation of the line that is parallel to the first line and passes through (2, –1)?

A.
4x – 2y = –6
B.
y = 2x – 5
C.
y = 3x + 4
D.
2x + y = –1

Answer 1

parallel lines means slope same so the slope of the reqired line will also be 2.
y- (-1) = 2(x-2) is the req line (y- y coordinate) = slope(x-x coordinate)
y+1=2x-4 .....
y= 2x - 5

Answer 2

ankitshaw, I appreciate it! :)
