    You are given the slope of the line which you are to find. Where you say? It is given that it is parallel to the line y=2x-3, parallel lines have equal slope so the slope of the line you are to find is 2. (the coefficient of x).

    Secondly you are given a point (-2,3) which the line you are to find passes through. What else could you want?

    You can now use the equation: m=(y-3)/(x-(-2)) and obtain the equation of the desired line you are to find.

    Plug in 2 for m and solve.

    Let me double check my work. 2 (y -3) -- = ----- cross multiplying 1 (x +2) 2x+4 =y - 3 y=2x + 7 appears to be correct

    How did you come up with the -5

    *I think I see what you did, you didn't treat the double negative correctly.

    x - (-2) becomes x + 2

    y-1=m(x-x1) y- -1=2(x-2) y+1=2(x-2) y+1=2x-4 -1 -1 y=2x-5

    it is x - (-2) That becomes x+2

    Do you see that? The P is (-2,3) x=-2, y=3

    All other operations were correct, you're almost there.
