What is the equation in point slope form of the line that passes through the point (1, −2) and has a slope of 3? y+2=3(x−1) y−1=3(x+2) y−2=3(x+1) y+1=3(x−2)

point slope form

y-y1 = m(x-x1)

y-(-2) = 3(x-1)

y+2 = 3(x-1)

Choice A

the first one, all those points on the line just make a strait line.

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
