Answer:
Function A is linear. Equation of A is <em>y = 1.67x +0</em>
<u>explanation</u>:
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 <em>two points </em>from table: ( 3, 5 ) , ( 6 , 10 )
use the slope formula to find slope:
:
: <em> or 1.67 ..</em><em>.this is slope in 2 decimal places, m</em>
then formula to find equation: y - y1 = m( x - x1 )
: y - 5 = 1.67 ( x - 3 )
: <em>y = 1.67x +0</em>
