1.) left 2, up 3 4.) right 2 up 3
Slope is rise over run
I would suggest writing the coordinate that is farthest to the left first so it is easier to visualize (-1,-6),(2,3)
as you go to the right, it goes over three, and up 9
9/3 simplifies to 3
the slope is 3
Answer:
20°
Step-by-step explanation:
The sum of angles in a ∆ = 180°
Therefore,
Use this expression to find the value of x, then find the measure of angle A.

Subtract 20 from both sides


Divide both sides by 20


Find measure of angle A.
Angle A is given as 
Plug in the value of x and solve

Using a system of equations, it is found that there are 34 pop songs are on the playlist.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Number of hip-hop songs.
- Variable y: Number of pop songs.
Brandon has a playlist with 83 hip-hop and pop songs, hence:
x + y = 83.
There are 15 more hip-hop songs than pop songs, hence:
x = 15 + y.
Replacing the second onto the first equation:
x + y = 83.
15 + y + y = 83.
2y = 68.
y = 34.
There are 34 pop songs are on the playlist.
