<h3>Answer:  D) 7</h3>

===================================================

Explanation:

a31 means "the value in the third row, first column". That value is 7

As another example, a22 = 3 since 3 is in the second row, second column.

Another example: a12 = -1 because we're in the first row and second column.

This is a 3x2 matrix due to it having 3 rows and 2 columns.

Answer:

1.  y = x + 7

Step-by-step explanation:

Find the slope

Choose two points and find the slope using rise/run

(1,8) (2,9)

9-8/2-1

1/1 = 1 = m (slope)

Find b using the slope and one point

m=1   (1,8)

8 = 1 (1) + b

8 = 1 + b

7 = b

Fill in m and b into y = mx + b

y = 1x + 7
