For the graph y = -8 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your answer with two or more sentences.

Perpendicular slope: undefined

Parallel slope: zero

Step-by-step explanation:

y = -8 results in a horizontal line crossing -8 on the y-axis, with a slope of zero: 0/-8. A vertical line would be perpendicular and has an undefined slope because 0 is the denominator . A line parallel to y = -8 would be any line with a slope of zero and crosses the y-axis. Parallel lines have the same slope.

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 : )
