Write the equation of the line that is parallel to the line 3x − y = −3 and passes through the point (4, −2).

y = −x − 6

y = −x − 14

y = 3x − 6

y = 3x − 14

Question

Write the equation of the line that is parallel to the line 3x − y = −3 and passes through the point (4, −2). 

 y = −x − 6 

 y = −x − 14 

 y = 3x − 6 

 y = 3x − 14

swissgirl · Answer

ok if its parallel all it means is that it has the same slope
3x-y=-3 can be rewritten as y=3x+3
which is in the form of y=mx+b where m is our slope
so what is the slope for this line?

campbell_st · Answer

the easy way is the substitute the point into the 4 lines... only one will return the correct answer

or take you line and rewrite it in point slope form

y = 3x + 3

find the slope
