Does your line have slope +1/2?
Does your line pass through (4,-2)?
If both answers are "yes", you are done. Feel free to be confident in your result.
My answer is y = 1/2x+0, but I'm not sure if my math was right
1/2 = y - (-2)/ x-4
1/2(x-4)=y - (-2)
1/2x -2 = y+ 2
1/2x+0=y
Can anyone tell me their answers, and show me where my work was wrong? I'm pretty confident that I got it right though.
You may wish to check the sign on your constant term. It should be -4, not +0.
Also, be more careful with Order of Operations. y - (-2)/x - 4 is absolutely NOT the same as [y - (-2)]/[x - 4]
Similarly, 1/2x is NOT the same as (1/2)x.
