Answer 1

Answer: Funciton A is linear. Its equation is y=1.66~(x) + 0

Explanation:

See if this works. I’m not 100% sure!

Answer 2

Function A is linear. Equation of A is y = 1.67x +0

explanation:

Function B shows that its not a linear function as the slope changes. Linear function always has the same slope. So function A is linear. and proportional in every step. Visual image given below.

To find the equation of A:

Take out two points from table: ( 3, 5 ) , ( 6 , 10 )

use the slope formula to find slope:
`(y2-y1)/(x2-x1)`

:
`(10-5)/(6-3)`

:
`(5)/(3)` or 1.67 ...this is slope in 2 decimal places, m

then formula to find equation: y - y1 = m( x - x1 )

: y - 5 = 1.67 ( x - 3 )

: y = 1.67x +0
