Question

Linear or non linear

Answer 1

Linear equation.

Step-by-step explanation:

It is linear as y increases 11 grids with every increase in x grid.

OR,

I will make a linear equation from two coordinates: (1,11),(2,22)

slope:
`(y2-y1)/(x2-x1)` →
`(22-11)/(2-1)` →
`11`
`is`
`the`
`slope`

the find equation using:

y - y1 = m(x - x1) → y - 11 = 11(x-1) → y = 11x ....this is linear equation.

Therefore it's linear.

OR,

Then check if 3rd and 4th coordinate matches the equation.

y = 11x y = 11x

y = 11(3) y = 11(4)

y = 33 ...therefore matches y = 44...therefore matches

So, its a linear equation.
