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.
The y-intercept is being changed. In the equations given we are using the formula (y=mx +b), b means the y intercept. In this we are changing the y intercept from 2 to -1. There is nothing else being changed.
Answer: y-5=2/3(x-2)
Step-by-step explanation:
Point-slope formula: y-y1=m(x-x1)
M=slope
Slope is 2/3
Plug in your x and y
