A line that includes the point (-9, -2) has a slope of -9. What is its equation in point-slope

9x- y = 79

Step-by-step explanation:

Use the formula    y - y1 = m (x - x1)

point: (-9,-2)  x1= -9   y1= -2

slope: -9

plug everything in    y + 2= -9 (x + 9)

simplify   y + 2= -9x - 81

move the 2 to the other side    y = -9x - 79

move the -9x to the other side    -9x + y = -79

multiply the whole thing by -1 to make the x positive

9x - y = 79

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 : )
