A line has this equation: y=-3x+7 Write an equation for the parallel line that goes through (-4,-8)

Given:

The equation of line is .

A line is parallel to given equation and passes through the point (-4,-8).

To find:

The equation of parallel line.

Solution:

The equation of a line is

On comparing this equation with , we get

So, slope of given line is -3.

We know that, slopes of parallel lines are equal. It means, the slope of the parallel line is also -3.

The parallel line passes through (-4,-8) and having slope -3. So, the equation of line is

Therefore, the equation of parallel line is .
