1. The x-coordinate of (-5,3)

Normally, we write a point with x-coordinate x and y-coordinate y as (x,y). So, The x-coordinate of (-5,3) is -5

2. The slope through the points (-2,5),(6,-3)

Use a formula k=(y2-y1)/(X2-X1), WE GET The slope through the points (-2,5),(6,-3) as follows.
k=(y2-y1)/(X2-X1)
=(-3-5)/(6-(-2))
=(-8)/8=-1

3. The y- intercept of ...
