Question 346422
Hi,
You need to know the equation of the line or two points on the line  to connect or the slope of the line and a point on the line.  For ex, if you know the equation of the line:for ex, y=2x +1.  That crosses the y-axis at (0,1)and as y increases by 2, x increases by one. Hint: slope = 2/1
