    Parallel lines have the same slope.

    The given line has equation: y = 2x + 3 That means the slope is 2. The parallel line also has slope 2.

    A and B are parallel to the given equation as @mathstudent55 mentioned in the previous post

    The parallel line has equation y = 2x + b Now we need to find b. We use the given point for x and y and solve for b. -1 = 2(2) + b -1 = 4 + b -5 = b Since b = -5, the equation of the parallel line is y = 2x - 5
