Coordinate gemoetry help

Find the equation of the line through the point (-2,1) parrellel to Y=1/2x -3 I know as its parallel it will have the same gradient, but i'm not too sure how to approach the question.

You do know this is your 2nd thread, asking for help on the same question

You have a point (-2,1) and a gradient so use the formula:
y - y1 = m(x - x1) where m is the gradient and x1, y1 are the co-ordinates of your point :smile:

As it is a straight line, another way of doing it is by using:
y=mx+c

Where you have m, the gradient, and you have y and x from the question.
This gives you c, and then you have the equation of the straight line.
