Find the equation of the line through point (−5,5) and perpendicular to y=5/9x−4. Use a forward slash (i. e. "/") for fractions (e. g. 1/2 for 1/2).

Step-by-step explanation:

Given

Passes through

Perpendicular to

Required

The line equation

First, we calculate its slope (m)

In , the slope is:

This is so because, the gradient intercept is:

By comparison, you have:

Since the required line and are perpendicular, then the slope (m2) is:

The equation is then calculated using:

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
