The surface area of the Arctic Ocean is approximately 315 square kilometers. The surface area of Lake Ontario is approximately 39 square kilometers. How many lakes the size of Lake Ontario will it take to equal the surface area of the Arctic Ocean?

3x + 4y -25 =0 represents the amount of change sianna should recieve

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

i think the answer is c sorry if it's wrong
