Help with this question not sure why it’s confusing me

see below

Step-by-step explanation:

We have two points, so we can use the slope formula

m = ( y2-y1)/(x2-x1)

    = ( -6- -6)/( 6-3)

     = ( -6+6)/( 6-3)

    = 0/3

  = 0

The slope is zero

This means that it is a horizontal line  ( the y value does not change)

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
