Can someone answer the whole thing ? I’ll give points

y - 27 = 8(x - 3)

Step-by-step explanation:

First find slope and then use point slope form to get required equation.

y-3=8(x-27)

Step-by-step explanation:

1. Find the slope

The equation to find slope is (y2-y1)/(x2-x1)

Substitute:

(27-(-61))/(3-(-8)

= (27+61)/(3+8)

=88/11

=8

2. Use a formula to finish the problem

Use the formula*

y - y1= m(x-x1)

Substitute:

y-3=8(x-27)

*An explanation of the formula [y - y1= m(x-x1)]and how to use it:

This formula is used in order to figure out the equation of a line. The equation is the "y=mx+b" format.

y = just the y used above

m = The slope of the line (in this case, 8)

x = The x used above

b = Whatever else is added to mx in order to make y

Next, look at the formula used to find the equation of a line.

y - y1= m(x-x1)

y = the y used above

y1= one of the y coordinates. the "1" part is added so there is no confusion between the actual coordinate and the y that is used as a placeholder. Also, you can use the y from any coordinate. It is just so there is no confusion

m = the slope.

x = the x used above

x1 = the x coordinate that goes with the y one. the "1" part is added so there is no confusion between the actual coordinate and the y that is used as a placeholder. Note that the "one" is the same. When you find the slope of a line, you always line it up so the "y1" is above the "x1" This is the same thing.

When choosing one of the points, choose the easiest set to simplify.

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
