the question is "y= 2x + 1" and it needs to be graphed. Do I divied 2x by 2? Also does that make the y intercept 1? Im just checking my answer :)

Best ResponseYou've already chosen the best response.0the x intercept is certainly 1, because \((0,1)\) is on the graph

Best ResponseYou've already chosen the best response.0and no, you do not divide by anything pick an x, find the y, plot the point for example, if \(x=2\) then \(y=2\times 2+1=3\) so \((2,3)\) is on the graph

Best ResponseYou've already chosen the best response.0so can you walk me through the problem how it should be done so I know for next time?

Best ResponseYou've already chosen the best response.0i thought i just did, but we can go slower if you like you know the y intercept is 1, because you said it, so \((0,1)\) is on the graph dw:1440292521307:dw

Best ResponseYou've already chosen the best response.0now the slope is \(2\) which means for every increase of 1 in x, the y values decreases by 2

Best ResponseYou've already chosen the best response.0Oh, so do I just plot 2 on the xaxis?

Best ResponseYou've already chosen the best response.0but we can do ahead and plot a few points then connect the dots

Best ResponseYou've already chosen the best response.0lets put \(x=1\) and see what \(y\) is

Best ResponseYou've already chosen the best response.0if \(x=1\) then \(y=2\times 1+1=2+1=1\) so the point \((1,1)\) is on the graph

Best ResponseYou've already chosen the best response.0maybe now pick \(x=2\) then if \(x=2\) you have \[y=2\times 2+1=4+1=3\] so now we know \((2,3)\) is on the graph

Best ResponseYou've already chosen the best response.0once you have a few points plotted, they should line up nicely and you connect the dots to get your line
