Question

Cx+y=-4
What can you conclude about this family of lines?

Answer 1

Not exactly sure what to do or plug in here...
Would be different if C was a definite value rather than a variable...

Answer 2

y = -cx-4
has a slope of -c and y intercept of -4

Answer 3

this question asks for the "family" of lines... in other words, what do they all have in common, no matter what C is...

if you rewrite the equation in slope-intercept form, you'll get: \(\large y=-Cx-4 \)
so according to this, the family of lines all intersect the y-axis at -4.

Answer 4

I don't see how that it's any different then what I said @ByteMe
