AWARD AND FAN!! ALGEBRA 1

Choose the equation below that represents the line passing through the point (2, –4) with a slope of one half.

y = one halfx + 5
y = one halfx − 3
y = one halfx − 5
y = one halfx + 3

C

curry · Answer

2(1) - 5 = -4

mysangels · Answer

You can just substitute the coordinate into the equation. Do you understand?

priyar · Answer

don't give direct answer @Curry we must help arrive at the answer...

anonymous · Answer

So -4 = 1/2(2) + 5 would be the first option?

mysangels · Answer

Yes.

curry · Answer

Hmm, that would evaluate to 6. YOu want it to evaluate -4

anonymous · Answer

and then i just keep replacing y and x with the coordinets?

anonymous · Answer

okay

mysangels · Answer

Yep. It's as easy as that.

curry · Answer

So, you shouldn't just plug in aimlessly. You should just plug in x, into each equtaion and see which one gives you correct y.

mysangels · Answer

When both sides equal each other, you have the right answer.

anonymous · Answer

okay, thank you so much guys!

mysangels · Answer

Anytime! ^-^

anonymous · Answer

can you guys medal each other so you both get the award?

danjs · Answer

That is a good last resort for a test with multiple choice answers when you don't know how to do the problem.
The point - to understand how to put together a linear equation from a point (x,y) and a slope direction.
