Write an equation of the line through the point (-3,-8) and perpendicular to the line x = -7.

The slope of the x = - 7 equals infinite...

We know that the slopes of the perpendicular lines are inverse and symmetrical to each other ;

So ;

This the slope of the line.....

_________________________________

We have following equation to find the line :

Now just need to put the coordinates and the slope ;

Look :

And we're done....

Thanks for watching buddy good luck.
