# How do you write the equation that represents the line perpendicular to y=-3x+ 4 and passing through the point (-1, 1)?

##### 1 Answer

#### Answer:

#### Explanation:

First, we need to determine the slope of the perpendicular line.

If the slope of a line is

Because the equation for the line we are given is already in slope-intercept form we can obtain the slope.

Slope-intercept form is

So, the slope of the line given is:

Now that we have the slope and a point we can use the point-slope formula to determine the equation for the perpendicular line.

The point-slope formula is:

Where

To convert to slope-intercept form we can solve for
