Write an equation of a line whose graph is parallel to the graph of y = 3x – 10.

Question

lgbasallote · Answer

hint: the slope of that line is 3. so what do  you think will be the equation of the parallel line?

anonymous · Answer

-3? @igbasallote

lgbasallote · Answer

nope. remember: parallel lines = same slopes

anonymous · Answer

Ah, sorry i guess i am not understanding

jim_thompson5910 · Answer

y = mx+b

y = 3x+b ... Plug in the slope m = 3

From here, you can make up any number for b and it will be your answer

lgbasallote · Answer

parallel lines have the same slopes

perpendicular lines have negative reciprocal slopes

what don't you understand?

@jim_thompson5910, Igbasallote, so y=3x + 5? would be parallel then?

jim_thompson5910 · Answer

yes, so are

y = 3x+10
y = 3x+22
y = 3x - 16
...etc etc

jim_thompson5910 · Answer

as long as it has a slope of 3, it will be parallel

anonymous · Answer

Ok @jim_thompson5910, so my answer of y=3x + 5 would be correct for the question?

jim_thompson5910 · Answer

yes it would be
