If you arrange this properly in the slope intercept form (y=mx+b) so just make it arranged in this format.
4x-7y=-28
Subtract 4x
-7y=-28-4x

Rearrange.
-7y=-4x-28
Divide by -7
y=4/7x+28
The number next to x is your slope and the other number is your y-intercept.

2x - 7y =28
-7y = -2x +28
-7y/-7 = -2x +28/-7
y = 2/7x -4

It’s C since it is open and x is less than 2. We can plug in any number on the number line to see if this makes sense.

so the equation is to be like x = c

but it is passing (2,13)

so the equation is

x= 2
