Question

Linear or non linear

Answer 1

Answer:

Linear equation.

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: $\frac{y2-y1}{x2-x1}$ → $\frac{22-11}{2-1}$ → $11$ $is$ $the$ $slope$

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.
