Question 627628: Write an equation of the line that is parallel to the given line
y = 2x + 3 and the given point (-4,1). Found 2 solutions by solver91311, ewatrrr:Answer by solver91311(24713) (Show Source):
The given equation is in slope-intercept form, therefore the slope of the graph of the given equation can be determined by inspection of the coefficient on . Parallel lines have equal slopes.
Use the point-slope form of an equation of a line to derive the desired equation:
where are the coordinates of the given point and is the slope of the graph of the given equation.

My calculator said it, I believe it, that settles it
Hi,
Write an equation of the line passing thru pt(-4,1) that is parallel to the y = 2x + 3 ( m = 2)
New Line: parallel lines have the same slope
y = 2x + b
1 = | Using Pt(-4,1) to find b
9 = b
y = 2x + 9
