An equation of a line through (0,2) which is perpendicular to the line y=4x+4 has slope and y-intercept

Slope of the line is -1/4 and y intercept is 2.

Step-by-step explanation:

Let the equation of the required line be given as

The required line is perpendicular to the line

Slope of the line is 4.

So the equation of the line becomes:

But this line passes through the point (0,2).

So the equation of the line is :

Its slope is -1/4 and y intercept is 2.

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 : )
