Question

What is the rate of this answer ??

Answer 1

Option (4)

Explanation:

Let the input output values of the table are represented by the equation,

y = mx + b

Here m = rate

b = y-intercept

Since, at x = 0, y = -1 [Point given in the table]

y-intercept 'b' = 0

Rate =
`(y_2-y_1)/(x_2-x_1)`

Where
`(x_1,y_1)` and
`(x_2,y_2)` are two points given in the table.

If the points are (-2, -5) and (-1, -3),

Substitute the values in the formula,

Rate =
`((-5)-(-3))/((-2)-(-1))`

=
`(-5+3)/(-2+1)`

= 2

Therefore, Option (4) will be the answer.
