    first rewrite both equations so they are each in the form y=mx + b you can easily tell the answer then (I will help if oyu write the equations in that form...)

    in the first equation add 2x to each side do that one first

    just add 2x to each side and write the resulting equation here

    −2x + y = 3 2x 2x

    In that case I'm afraid you don't have the background skills to answer a question like this. You should go back to study simple equations, and how to re-arrange them, and then come back to these 'systems of equations'

    no one can 'explain' this in time for you to do an exam. you need to re-arrange the 2 equations so that they look lik e y=mx+b get the y term on one side, and the other terms on the other side you must have done this in your class if it being set in an exam (and btw - why are you asking exam questions here?)

    ok so both the equation represent 2 lines the standard equation of a line is--->ax+by+c=0 suppose we have 2 lines say-\[a_{1}x+b_{1}y+c_{1}=0\]and\[a_{2}x+b_{2}y+c_{2}=0\] the lines are overlapping if-\[\frac{ a_{1} }{ a_{2} }=\frac{ b_{1} }{ b_{2}}=\frac{ c_{1} }{ c_{2}}\] the lines are parallel if-\[\frac{ a_{1} }{ a_{2} }=\frac{ b_{1} }{ b_{2}} \neq \frac{ c_{1} }{ c_{2}}\] and intersecting if-\[\frac{ a_{1} }{ a_{2} }\neq\frac{ b_{1} }{ b_{2}} \neq\frac{ c_{1} }{ c_{2}}\] so we have 2 equations that is we got 2 lines i'll jst give u some hint then u can do it ..if u get any prblm jst ask :) so lets take the 1st line -2x+y=3 we need to convert it to this form-->ax+by+c=0 so basically we want 0 on the right so we subtract 3 from both sides -2x+y-3=3-3 -2x+(1)y-3=0 comparing this with ax+by+c=0 we get a=-2 b=1 and c=-3 now we have a,b,c of 1st line find a,b,c of second line and then apply the thing i wrote up there^ :) which ever satisfies is ur answer

    yeah - like she'll understand that if she won't add 2x to each side.....

    so it would be intersecting right? @imqwerty
