Question

Which of the following represent a line parallel to y-axis. a. 2x + 3y = 5 b. x + y = 2 c. y – 3 = 0 d. 3x – 4 = 2x – 1

Answer 1

Step-by-step explanation:

(i) 3x + 5y = 7.5

This can be expressed in the form ax + by + c = 0 as 3x+5y+(−7.5)=0.

(ii) 2x−y5+6=0

This can be expressed in the form ax + by + c = 0 as 2x+(−15)y+6=0

(iii) 3y – 2x = 6

This can be expressed in the form ax + by + c = 0 as 2x+(−3y)+6=0.

(iv) 4x = 5y

This can be expressed in the form ax + by + c = 0 as 4x−5y+0=0

(v) x5−y6=1

This can be expressed in the form ax + by + c = 0 as 6x−5y=30

(vi) 2–√x+3–√y=5

This can be expressed in the form ax + by + c = 0 as 2–√x+3–√y+(−5)=0

Answer 2

Answer:

Step-by-step explanation:

y-3 = 0

or y=3.

Its a line through y=3 and is parallel to x axis.
