(19 + 28 + 62 + 51 + x) / 5 = 38
(160 + x) / 5 = 38
160 + x = 38 * 5
160 + x = 190
x = 190 - 160
x = 30 <== age of 5th person

Hey there! :D
Plug it into slope form:
m= (y2-y1)/(x2-x1)
m= (0-(-9)/(-2-0)
m= (0+9)/(-2-0)
m=9/-2
m=-4.5 <== the slope
I hope this helps!

Well if the nonfiction books to novels ration is 3:2
we can say that we have x number of nonfiction books and then the relationship would be represented by this equation:
2x = 3y
where x are the number of nonfiction books and y the number of novels.
And for the novels and cookbooks to be 3:1
we can write the equation:
y = 3w
where y are the novels and w the number of cookbooks
