Use the formula for average rate of change over an interval of two points:

$\frac{y_2 - y_1}{x_2 - x_1}$

We have two points: (-2, -1) and (0, -1). Plug the values into the formula:

$\frac{-1 - (-1)}{0 - (-2)} = \frac{0}{2} = 0$

The average rate of change over the interval [-2,0] is 0.

Plz can someone help me show work for these two problems!! 3x + y = 13 2x - y = -1

Alisiya [41]

Answer:

3x +y = 13

Or, x=13-y/3......eqn(i)

Now putting the value of x

2x - y = - 1

Or, 2(13-y/3) - y = - 1

Or, 26 - 2y /3 - y = -1

Or, 26 - 2y - 3y = - 3

Or, 26 - 5y = - 3

Or, - 5y = - 3 - 26

Or,y = - 39/ (- 5)

Or, y = 7.8~
