The rate of change of the function represented in the table is

The rate of change is -12

Step-by-step explanation:

The rate of change can be calculated knowing two pairs of points from the linear function as:

m (rate of change, which is also the slope of the function)= y1 - y2 / x1 -x2

then,

(x1,y1)=(3,-2)

(x2,y2)=(5, -26)

m=(-2+26)/(3-5) = -12

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
