Write an equation of a line that passes through the point (7, 3) and is parallel to the line y = negative 2 over 3x + 3. y = 3 over 2x − 3 y = 3 over 2x + 3 y = negative 2 over 3x + 23 over 3 y = negative 2 over 3x − 23 over 3

    ok, I recommend using the slope-intercept equation. do you know what that one is?

    perfect, so they gave you an x and a y when they said it passed through (7,3) so start by plugging that in.

    good, now if 2 lines are parallel, what does that mean for their slopes?

    What do you mean by plugging the fact that they have the same slopes then?

    plug in the slope and the y-intercept and you have your equations.
