Answer:
How can we answer when no graph illustrations is shown
Step-by-step explanation:

is equivalent to <span>

That is in the form </span><span>

which is point slope form
In this case,
m = 1/2 is the slope
(x1,y1) = (7,-8) is the point the line goes through</span>
Convention in algebra is that we use letters such as a, b, c, etc., for parameters and letters such as x, y z, and so on, for variables.
Thus the parameters here are a, b and k. k is the constant of proportionality.
