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

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

right, and of y=2x-7 ?

it is too 2

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

ok. But how to satisfy a point to it ?

OpenStudy (shubhamsrg):

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