Answer 1

Answer:

(0,-41)

Step-by-step explanation:

Let see if this table of values are proportional.

• All x values decrease by -9.
• All y values decrease by -19.

This mean that the function is proportional. This also gives us the slope which is 19/9.

This tell us that this function will be a linear function since we are trying to find the y intercept we would use this equation

We know the slope and we know a point so let use point slope form to find the intercept.

$y - y _1= m(x - x _1)$

Let use points (-18,-79) and let m =19/9.

$y + 79 = \frac{19}{9} (x + 18)$

$y + 79 = \frac{19}{9} x + 38$

$y = \frac{19}{9} x - 41$

This is in slope intercept form so the y intercept is

$- 41$

The answer is -41.
