anonymous one year ago need help!?!?!?!?! will give medal Choose the equation below that represents the line passing through the point (1, −4) with a slope of one half. y − 4 = 1/2(x − 1) y + 4 = 2(x − 1) y + 4 = 1/2(x − 1) y − 4 = 2(x + 1)

1. anonymous

do you know your forms? Point-Slope, Standard and Slope-Intercept?

2. anonymous

yes but not sure how to apply them

3. anonymous

look at the info you are given... what info do you have?

4. anonymous

also, look at the answers... what form are the answers given in?

5. anonymous

the point (1,-4) and slope 1/2

6. anonymous

so you have a point and a slope... what form could you easliy put these into to get an equation for the line?

7. anonymous

point-slope?

8. anonymous

9. anonymous

y-y=m(x-x) so... y-(-4)=1/2(x-1)

10. anonymous

simplify a bit...

11. anonymous

y+4=1/2x-1/2

12. anonymous

too much... don't simplify the right side.

15. anonymous

just making sure, I think the answer is c though

16. anonymous

well, be confident! justify and then testify!

17. anonymous

lol THE ANSWER IS C !!!!! thanks

18. anonymous

$$y-y_1=m\left( x-x_1\right)$$ YES!!! AWESOME!!!
