# coordinate geometry help! Watch

1. I would appreciate some hints on how to answer this question:

Q) The straight line L has the gradient 3 and passes through A(-6,4)
1) find the equation for this line. (I worked this out to be y=3x+22)

2) line M crosses the y-axis at point B and intersects at point C, therefore work out points B and C.

This is the question i need help with ^^ I know that M crosses the y axis at point b, so i know the x coordinate for B is 0. However, i am unsure how to work out any other points.

Thanks

At Y-axis , x coordinates are 0 and at X-axis , y coordinates are 0.
