Question

Choose the equation of the line passing through the point (1, -5) and parallel to y = 2x + 4.

y = -2x + 7

y = 2x - 3

y = 2x - 7

y = -2x + 3

Answer 1

@shubhamsrg

Answer 2

any guesses ?

Answer 3

No I don't have clear concept of this chapter

Answer 4

you can atleast judge by hit and trial which line/s satisfies (1,-5).

Answer 5

y = 2x - 7

Answer 6

and that will be your answer

Answer 7

can you tell me slope of y = 2x + 4 ?

Answer 8

its 2

Answer 9

right, and of y=2x-7 ?

Answer 10

it is too 2

Answer 11

then you should learn this as a fact : parallel lines have equal slopes.

and hence your answer.

Answer 12

ok. But how to satisfy a point to it ?

Answer 13

y=2x+c is your answer
satisfy that point on it to get the value of c

Answer 14

ok I got Answer is C : y = 2x - 7
is it correct ?

Answer 15

you had this right in the first place by hit and trial only.
hmm, right answer

Answer 16

Thank you Sir
