Question

Find an equation of the line containing the point (-1,3) and parallel to the line x+2y=-6.

Answer 1

If two lines are parallel, what do you know about their slopes?

Answer 2

@nikato don't they have the same slop

Answer 3

Right, so can you find the slope of the given line?

Answer 4

y=3-(1/2)x @nikato

Answer 5

Ok, so your slope is -1/2.

Now using the point slope form, plug int he new points (-1,3) and the slope to find the equation of ur new line.
