    First off you need to find the x and y coordinates

    okay so, first when x=0 what is y

    y=-2x+490 when x=0 the equation becomes y=-2*(0) + 490 =490 so we have this point (0,490) graph this first

    y=-2x+490 this line is given in slope intercept form y=mx+b we saw how b or 490 was the y intercept now -2 is where m is, -2 is the slope

    slope tells you the change in y for change in x a slope of -2 means that for 1 change in x we go down by 2

    490 is a huge number so this is not drawn much to scale but thats about it

    okay sure! another way to do this would be to find any 2 points from your given equation and just connection

    for example we found a point (0,490) by setting x=0

    you can find other points by setting x = anything you want

    generally though, what people do is find the y when x=0 and find the x when y=0 so for your equation y=-2x+490 we set x=0 and get y=-2*0 + 490 =490 so one point is (0,490) For the 2nd point we set y=0 0=-2x+490 now we solve for x 2x=490 x=490/2 =245 (245,0) is other other point |dw:1435269561978:dw|
