Question

will fan and give medal:)
Which is NOT true about the following table?

A)it shows a linear function
B)x increases by 1 each time
C)the rate of change is not constant
D)y increases by a different value each time

Answer 1

@Nnesha

Answer 2

okay what do you think ?
i want to see what you already know :-)

Answer 3

@Nnesha well i already know b and d are true so I'm stuck on if its a or c

Answer 4

great so do you know what it's mean by constant ?

Answer 5

average rate of change = slope

Answer 6

no thats what I'm stuck on @Nnesha

Answer 7

okay you have to find slope of the table
constant term meaning slope is 0
when slope is 0 you would get horizontal line
meaning only x values are increasing while y values stays same
so find slope

Answer 8

the slope is y = 5x − 4 @Nnesha

Answer 9

that is equation

Answer 10

so what am i trying to do "/

Answer 11

@Nnesha

Answer 12

which 2 points did u use ?

Answer 13

1,1 and 4,16

Answer 14

great your equation is right now choose another point and seee if you get equal sides

Answer 15

(2,4)
y =5x -4
replace x and y by their values let me know what you get

Answer 16

A is the correct answer

Answer 17

okay why do you think is it A ?

Answer 18

it is*

Answer 19

cause c is true

Answer 20

yes that's also right
all tables values should be solution of the equation
linear function when values are increasing or decreasing by a same value

Answer 21

so I'm good :)

Answer 22

yep right
btw last option give us a big clue
y values are increases by a different value
gO_Od to go!
