When you use counters to model the sum of two integers with different signs, how do

you know the sum is negative? Complete the explanation.

When using counters to model two integers with different signs, having ("fewer",

"more") positive counters than negative counters means that the of the

["difference", "sum") integers is negative.

a fewer, sum

b. fewer, difference

c. more, sum

d. more, difference

0 is its x and y coordinate

answer: the first graph

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
