The point slope form is
y-y1=m(x-x1)
where
m=slope
and you are given a point (x1,y1)
we are iven that slope=2
and a poin is (3,10)
3=x1
10=y1
y-10=2(x-3)
the answer is
y-10=2(x-3)
There are three terms in alg exp
-12 + 18 = 70 - 64 or(-12+18)+(6*12)-2
Find factors of 12 and 21
Divide 3 from both numerator and denominator.
(12/21)/(3/3) = 4/7
4/7 is your ratio equivalent to 12/21
hope this helps
