Given:

The equation of a line is:

A line passes through the point (-5,-3) and perpendicular to the given line.

To find:

The equation of the line.

Solution:

Slope intercept form of a line is:

                ...(i)

Where, m is the slope and b is the y-intercept.

We have,

         ...(ii)

On comparing (i) and (ii), we get

We know that the product of slopes of two perpendicular lines is always -1.

Slope of the required line is and it passes through the point (-5,-3). So, the equation of the line is:

Using distributive property, we get

Therefore, the equation of the line is . Hence, option A is correct.

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.
