How do you know that this is NOT the graph of [y=2x=3] ?

Question

graph: http://es.tinypic.com/view.php?pic=jfix6v&s=4

line: y=2x=3

show your work!!!!

IF you can,, explain.

Answer 1

do you mean y=2x+3?

ok, cool.

you know this because the slope (2) is positive.  if it was a negative slope (y= -2x+3) then it could be represented in that graph with the right y intercept.

if that doesnt make sense go to hotmath.com and search for graphs and eqations for graphs.

hope this helps!!

oh, and the equation y=2x+3 would be going from the left bottom corner to the right top corner roughly.

and, as explained above, the equation y=-2x+3 would go from the left bottom corner to the top right corner. :D
