Find the slope of the line.

a: -7
b: 1/7
c: 7
d: - 1/7

C: 7

Step-by-step explanation:

slope = rise/run

rise: vertical distance between two points

run: horizontal distance between two points

Start at point (-2, 2). You need to go to point (5, 3) by moving only vertically and horizontally. Go 1 unit up. The rise is 1. Now go right 7 units. The run is 7. You have arrived at point (5, 3)

slope = rise/run = 7/1 = 7

C: 7

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
