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

any guesses ?

No I don't have clear concept of this chapter

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

y = 2x - 7

and that will be your answer

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

OpenStudy (goformit100):

its 2

right, and of y=2x-7 ?

4 years ago
OpenStudy (goformit100):

it is too 2

OpenStudy (shubhamsrg):

then you should learn this as a fact : parallel lines have equal slopes. and hence your answer.

OpenStudy (goformit100):

ok. But how to satisfy a point to it ?

4 years ago
OpenStudy (shubhamsrg):

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

OpenStudy (goformit100):

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

OpenStudy (shubhamsrg):

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