+1006 y=mx+b
'm' is the slope (the steepness of the graph)
'b' is the y-intercept (where it hits the y-axis)
'y' is the y-value (height)
'x' is the x-value (length)
So the height is equivalent to the slope times the length plus the y-intercept. Pretty much, you can put in an 'x' value into a y=mx+b problem and get a 'y' value. In this case, the slope of the line is 1/5 and the y-intercept is 1.
Just plug in values, or use the on-site graph maker (there is a button on the bottom of the home page that says Create Graph). Helpful tip, remove the 'y=', or you'll get a dot!
