Answer:
31.5 or 63/2
Step-by-step explanation:
to do this, first you need to transform the <u>mixed number</u> <em>(3 1/2)</em> into an <u>improper fraction</u>, to get 7/2.
then you just multiply 9 by 7/2
9/1 (7/2)
63/2 = 31.5
<em>both of the answers in bold are correct</em>
The gradient or slope of a line is defined as
m=(y2-y1)/(x2-x1), we have points (-8,6) and (3,8)
m=(8-6)/(3-(-8))
m=2/11
-11
the answer is A
