Answer:
what's the question? I don't see anything
K is the slope of the line formed by connecting the points.
Use slope formula:

where the 2 points are the end points of the line (First and last going Left to right)

Substitute into slope formula

You can check if this is correct by going back to graph and going "up 7" and "over 2" to get from one point to the next.
I switched the x and y so it’s easier to see. The answer is (x-1)/(23).
I think it is tens or sum look up fractions place value and u will probable get it
I believe your answer is (1,5)
I graphed the equations and the ordered pairs and (1,5) is the only point that fell on both of the shaded areas.
hope this helps !!
