Explanation:

find slope (m)

m= 3- ( _5 ) / 6 - ( _10)

= 1 / 2

y = 1 / 2 x + c

to find - C

3= 1 /2 ( 6) + C

C= 0

y = 1 / 2 X

Answer:Step 1) Find the slope.

Step 2) Using the slope, one of the points and the point-slope formula determine the equation.

The slope can be found by using the formula:

m

=

y

2

y

1

x

2

x

1

Where

m

is the slope and

(

x

1

y

1

)

and

(

x

2

y

2

)

are the two points.

Substituting the points we are given in this problem the slope is:

m

=

10

8

2

6

m

=

18

m

m

m

m

=

Now we can use one of the points we were given, the slope we determined and the point-slope formula to find the equation for the line.

The point-slope formula states:

(

y

y

1

)

=

m

(

x

x

)

Where

m

is the slope and

(

x

1

y

1

)

is a point the line passes through.

y

=

9

2

(

x

6

)

If we want to put this into slope-intercept form we can solve for

y

:

y

8

=

9

x

(

)

y
