Y+3=-3(×+2)
Point slope form equation when graphed

The slope m = -3, and the point is (0,-9).

Step-by-step explanation:

The equation of a line in  slope-intercept form  is given as

                             y = mx + b

where m represents the slope and

           b represents the y-intercept.

⇒   y  +  3  =  −  3( x + 2)

subtract 3 from both sides.

⇒  y  =  - 3 x - 9

⇒ m  =  - 3 and the b  = - 9

Hence slope is -3 and y-intercept is -9

y-intercept = - 9 which is the coordinate point (0 ,-9)

To obtain any coordinate point on the line, select values for x and substitute them into the equation for corresponding value of y.

x  = -2 ⇒  y  =  -3 -2 - 9

y = 6 - 9 = -3

 Hence the another point on the line is (-2,-3)

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
