Explain how you can find the constant of proportionality from points on a graph representing a proportional relationship when it shows a point with an x value of one and if it doesn’t show an x value of one

Well all that I know is that if your plots on the graph pass through the orgin and form a straight line, then your ratios are proportional. Honestly that'sall i know.

Hope this helped a little bit though. Maybe it did maybe it didn't. Hope you pass your test though!!  :)

When the x-value is 1 , the y-value is the constant of proportionality. If there isn’t an x-value of 1, choose another point and divide the y-value by the x-value to find the constant of proportionality

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph
