Play ground 70% (TOTAL)
books 30% (TOTAL)
60% of the 70% are boys
20% of the 30% are boys
Does that sound about right for a start?
The expression 15t – 2t not equivalent to 2t – 15t because the negative sign in 15t – 2t belongs to the term 2t.
Solution:
Given expressions are 15t – 2t and 2t – 15t.
To determine 15t – 2t is equivalent to 2t – 15t or not.
Substitute t = 2 in above two expressions.
15t – 2t = 15(2) – 2(2)
= 30 – 4
= 26
2t – 15t = 2(2) – 15(2)
= 4 – 30
= –26
The values of the expressions are different when t = 2.
So, 15t – 2t is not equivalent to 2t – 15t.
Hence the expression 15t – 2t not equivalent to 2t – 15t because the negative sign in 15t – 2t belongs to the term 2t.

Answer:
y= (-7/9)(x-1)
Step-by-step explanation:
finding the slope:
slope= rise/run
rise= 7-0=7
run= -8-1= -9
slope= -7/9
point slope form:
y= (-7/9)(x-1)
