A it’s A because you’re combining those two things to get your answer
to get the slope of any straight line, we can simply use two points off of it, hmmm say let's use here (2,8) and (4,4)

X+23=2X+4
X-2X=4-23
-x=-19
X=19
You didn’t not show what is the relation between the expressions so I assumed it’s equall
.25 lbs= 4oz
4oz = 113.398 g
1g= 100cg
113.398 x 100
= 11339. 8 cg
