slope form y = mx + b; m is the slope

if the slopes are the same, the lines are parallel

7y+2x=4 2x 2x 7y = 2x + 4 is that correct?

correct one extra step y = 2/7x + 4/7 whats the slope

Ok so how would I go about doing a question that asked me this... slope intercept equation of the line whose graph is parallel to y=2x5 and has te yinterceot (0,9) There is no way I could do that one on my own!

surdawiBest ResponseYou've already chosen the best response.1
they are parallel so the slope will stay the same y  y1 = m(x x1) y  9 = 2*(x0) y  9 = 2x +9 +9 y = 2x + 9
