Please Help me plz! Thanks

Option D:

The equation of a line in point-slope form is y = 3x – 7.

Solution:

Take any two points on the line given in the graph.

Let the points be (–4, 4) and (2, 2).

Slope of the given line:

If two lines are perpendicular, then the product of their slopes are –1.

Multiply by 3 on both sides of the equation.

Multiply by –1 on both sides of the equation.

⇒

Perpendicular line passes through the point (2, –1).

Here, .

Using point-slope form:

Subtract 1 on both sides of the equation.

The equation of a line in point-slope form is y = 3x – 7.

Therefore option D is the correct answer.

step-by-step explanation:

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 : )
