Answer:
perpendicular
Step-by-step explanation:
x = 4 is a vertical line.
y = -2 is a horizontal line.
The lines are perpendicular.
Use PEMDAS
figure out everything inside the parentheses first, you still have to do PEMDAS inside of the parentheses also.
I will attach an image of how I got the first answer -7,867, sorry if my handwriting is sorta sloppy
To find slope between two given points:
(y2-y1)/(x2-x1)
Find the difference between the first two points
12-9.5/2-1 = 2.5/1 = 2.5
14.5-12/3-2 = 2.5/1 = 2.5
17-14.5/4-3 = 2.5/1 = 2.5
The rate of change between each point is 2.5
