Question 1071238
The two points one described and other given, are  (4,0) and (2,4).  One way to get the equation is plot the points and draw the line.  Measure slope m and read the y-intercept b, and fit into y=mx+b.



Stuffing everything together still needing to be simplified is this:


{{{y=((4-0)/(2-4))x+(4-((4-0)/(2-4))*2)}}}
