Asurf instructor has an initial fee of $12 and charges $8 per hour for lessons. explain how to determine what the y-intercept is and where it would be located on the graph.

The y-intercept in slope-intercept form is b, which is represented by 12. The y-intercept is the initial value, and is found on the graph as the point (0, 12) where the line crosses the y-axis.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
