Noob graph problem
I need help with the graph. I need to determine where the angle of the 2 points intersect with the max eg;(10,10) (-10, 10) outer box. I'm sure this is a simple formula but its been awhile :P Thanks in advance.
calculate the slope
Two points determine a straight line. From the graph, two points are (0,0) and (-4, 2.5). The line is -5x/8. When x=10, the point of interception is -6.25 when x=-10 the point of intersection is 6.25
