What is the equation of the line that is parallel to y=6x-1 and passes through the point (-3, 4). I’m super confused, any help would be great, thank you:)

Suppose a laboratory has a 30 g sample of polonium-210. the half-life of polonium-210 is about 138 days how many half-lives of polonium-210 occur in 1104 days? how much polonium is in the sample 1104 days later? 9; 0.06 g 8; 0.12 g 8; 2,070 g
