Answer:

y = 2x + 1

Explanation:

From the table attached,

x y Difference
[d=(y_2-y_1)]

-1 -1 -

0 1 1 - (-1) = 2

1 3 3 - 1 = 2

2 5 5 - 3 = 2

Since,there is a common difference 'd' = 2

Therefore, this table represents a linear equation.

Let the equation is,

y = mx + b

where 'm' is the slope and 'b' is the y-intercept.

Two points lying on the linear equation are (-1, -1) and (0, 1)

Slope 'm' =
(y_2-y_1)/(x_2-x_1)

m =
(1+1)/(0+1)

m = 2

And y-intercept 'b' = 1 unit

Therefore, equation of the line will be,

y = 2x + 1
