In order to answer this type of question, we need to remember that domain is set of first coordinates
based on that, the domain would be :
{2, 3, 8}
Hope this helps
This is simple you just need to think what minus or plus the variable in each equation (letter that represents an unknown number) equals what the equations do
No. 19 X= -8
No.20 R=10
No.21 X=0
No.22 B=7
No.23 V=-4
No.24 N=10
No.25 X=7
No.26 K=4
No.27 N=-4
No.28 X=-7
Hey there!
To find the equation of a line, we first have to determine its slope knowing that parallel lines have the same slope.
Let the line that we are trying to determine its equation be 
and the line that is parallel to be 
.
passes through the points (9 , 2) and (3 , -5) which means that we can find its slope using the slope formula:
⇒Subtitute the values :
.
Assuming that we want to get the equation in Slope-Intercept Form, let's substitute m = 7/6:
Slope-Intercept Form:
We know that the coordinates of the point (0 , -3) verify the equation since it is on the line . Now, replace y with -3 and x with 0:
Therefore, the equation of the line 
is

Multiply both sides by -8 to get k = -16
To check the solution, plug in -16 into the original equation. You do in-fact get 2
