The line ab has equation

the point a has coordinates (1, -1) and the point b has coordinates (3, k)

a) find the value of k

b) find an equation for the line through a which is perpendicular to ab

c) the point c has coordinates (-6 ,-2). show that ac has length

stating the value of p

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

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 : )

tried on you are knowing that we can't leave the picture in the graph ok no problem now you need to send it in the question group
