The measurement are the same. From 2,4,6,8. After you known those equal to 103. You know a line equals 180. So you would do 180-103=77. So from 1,3,5,7 will all be 77 degree.
Answer:

Step-by-step explanation:
We are asked to find the slope of a line. The slope tells us the steepness and direction of a line. It is found by dividing the change in y by the change in x.


In this formula, (x₁, y₁) and (x₂, y₂) are the points the line passes through. We are given the points (-6, 11) and (15,20). If we match a value with its corresponding variable, we see that:
- x₁ = -6
- y₁ = 11
- x₂ = 15
- y₂ = 20
Substitute the values into the formula.

Solve the numerator.

Solve the denominator. 2 back to back negative signs become a positive sign.


Simplify the fraction. 3 divides evenly into the numerator and denominator.


The slope of the line is <u>3/7.</u>
