Use a graph and a table to solve the system
{3y+6x=3
xy=7
and i'm suppose to have the two points where they intercept but i don't know how to do it.

Best ResponseYou've already chosen the best response.0You will get 2x+y=1 Then add the two equations. That will eliminate y and you can solve for x. can you do that?

Best ResponseYou've already chosen the best response.0Graph/Plot 3y + 6x = 3 Take 3y + 6x = 3 and turn it into slope intercept form 3y = 6x +3 3y/3 = 6x/3 +3/3 y = 2x + 1 in this equation we have our first point y = 2x + 1, which is the y intercept 1. plot (0,1) Now we have our first point (0,1) lets use our slope to find the next point. Our slope is 2x, so from (0,1) move down 2, since we are working with negatives, form the point (0,1), which will give us (1,1).Now plot the two points (0,1) and (1,1) and draw a line. do the same for the other equation and where the two lines cross is your answer. This is if you have to graph your work and show it

Best ResponseYou've already chosen the best response.0graph the 2 equations. the first one is 3y+6x=3 > y+2x =1 > y=12x the second one is xy=7 > x = 7+y > y = x7
