Use slope and y intercept to graph a line. y=2x-5

On your graph:-- Mark a dot on the y-axis, at y = -5 .-- From there, move 1 unit to the right and 2 units up and make a mark.  If this is too tiny for you, then you can move 7 units to the right and 14 units up, or11 units to the right and 22 units up ... any way you want to do it, as long as the distance 'up' is double the distance to the right, because the slope is 2 to 1.Wherever you wind up, mark a dot.-- Using your pencil and your ruler, draw a straight line between the two dots you have marked.  You may extend it as far as you wish in either or both directions.

m=2,b=-5 where m is the slope and b is the y-intercept
