Study this table. x y –3 –2 –2 0 0 4 4 12 which best describes the function represented by the data in the table? linear with a common ratio of 2 linear with a common first difference of 2 quadratic with a common ratio of 2 quadratic with a common first difference of 2

b: linear with a common first difference of 2

Step-by-step explanation:

Study this table.

x           y

–3       –2

–2         0

0           4

4          12

To check whether the given table represents linear function we check with the slope

use any two points from the table and find out slope

= 2

= 2

= 2

Slope is a constant 2 so it is a linear. common difference is 2

linear with a common first difference of 2

true

explanation:

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
