Step 1:

The coocrdinate points are $\"\"$ and $\"\"$ .

Find the mid point.

$\"\"$

Substitute $\"\"$ and $\"\"$ in the formula of mid point.

$\"\"$

The mid point of the coocrdinates $\"\"$ .

Step 2:

Find the slope.

$\"\"$

Substitute $\"\"$ and $\"\"$ in the formula of slope.

$\"\"$

Slope is $\"\"$

Write the slope intercept form.

By using mid point and slope to find the line equation of the slope intercept form.

General form of the slope intercept form is $\"\"$

Substitute $\"\"$ and $\"\"$ in the slope intercept form.

$\"\"$

The line equation of the slope intercept form is $\"\"$ .

Solution:

The mid point of the coocrdinates $\"\"$ .

The line equation of the slope intercept form is $\"\"$ .
