# How do you write the standard form of the equation of the line that is perpendicular to y=-4/3x-7 and contains (-5,-7)?

##### 1 Answer

The standard form equation is

#### Explanation:

The slope of our line is **negative reciprocal**.

The second condition is that the line contains

Substitute

So in slope-intercept form, the equation of our line is

but the question requires it in standard form. This means that it should be in the form

where
