Question

i worked it out.just need the answers..to see if i worked it out right please

Question 4
What is the y–intercept of 6x – 3y = 18?
Answer
A) (0, –6)
B) (0, –3)
C) (0, 6)
D) (0, 3)

Question 5
What is the equation of a horizontal line passing through (3, 10)?
A) x = 10
B) y = 3
C) x = 3
D) y = 10

Question 6
What is the equation of the line that passes through the point (2, 3) and is perpendicular to the line y = –x – 3?
A) y = x + 1
B) y = x + 5
C) y = –x – 1
D) y = –x + 5

Answer 1

What were the answers that you found?

Answer 2

wth, how are you meant to do the second one?

Answer 3

are you just meant to assume the line is horizontal?

Answer 4

A horizontal line is just in the form \( y = k \)
\( (x, k) \) is the set of all points on that line, where k is always the same and x can by any number. (So, its the same y-value parallel to the x-axis)

(3,10) is on the line, so y=10 must be the line equation since that is a horizontal line with y-value 10.
