slope = rise over run = y/x
A (-1,3) slope = 3/-1 = -3
B (1,2) slope = 2/1 = 2
C (-3,-1) slope = -1/-3 = 1/3
2 lines need to be negative reciprocals in order to be a right triangle
negative reciprocal of -3 is 1/3
so this is a right triangle

Answer:
y = 5
Step-by-step explanation:
A line parallel to the x- axis has equation
y = c
Where c is the value of the y- coordinates the line passes through
The line passes through (1, 5) with y- coordinate of 5, thus
y = 5 ← equation of line
Answer:
700 pages
Step-by-step explanation:
I first found out how many pages were in 1% so I divided 28 by 4.
I got 7 so I multiplied it by 100 and 700 was the answer.
Basically:
28÷4 = 7
7 x 100 = 700
I hope that kinda made sense!
