Best ResponseYou've already chosen the best response.0First find the intercepts. Plug in y=0. Plug in x=0.

Best ResponseYou've already chosen the best response.0Y=0 would give us x=5/2 X=0 would give us y=5

Best ResponseYou've already chosen the best response.0Now if you have drawn a grid. You can easily put atleast these two points in.

Best ResponseYou've already chosen the best response.0  <would be y=5 when x=0   ^    would be x=5/2 when y=0

Best ResponseYou've already chosen the best response.0Then comes our other piece of information: The slope. In our case it is 2. The negative tells us the line is "falling down". The 2 tells us that for every 1 in the xdirection the y changes by 2.

Best ResponseYou've already chosen the best response.0You can always try plugging in any X of your choice and the equation will spit back at you the Y that goes with it. So if you put in x=1, y= 2(1) + 5 = 3. You can plot the point (1,3) .

Best ResponseYou've already chosen the best response.0Sketching a curve means plotting ALL of these points! But if we know a few we can just connect the dots and it will give us a good idea what it looks like.

Best ResponseYou've already chosen the best response.0The negatives will cancel out. (1)*(1) = 1 or 1/1 = 1
