The third table on the top row. It has a linear function because the Y is always constant. For example: -3 + -2= -5 -5 + -2= -7
I don’t know put 2x on the x axis and dot 0 on the y axis
Add 4 to both sides to isolate the variable (-4+4=0) (2x+0=2x) (0+4=4) which leaves you with 2x=4 divide both sides by 2 to get rid of the number in front of the variable to get x by itself (2x/2=x) (4/2=2) therefore you’re left with x=2 (lo siento yo no hablo español la respuesta es x=2)
In that statement of a function, 'a', 'b', and 'c' all represent
plain old ordinary constant numbers.
You divide 14.99 by 5 which is 2.998. 1/5 off of 14.99 would be $ 11.99 rounded, because you subtract the 2.99 on 14.99
