Answer:
The equation of the line is,

Step-by-step explanation:
First, you have to write it in a form of y = mx + b :




When both lines are parallel to each other, they will have to same gradient value. So the equation of the line is y = (-2/5)x + b. Next, you have to find the value of b by substutituting (-10,3) into the equation :







now, if we take 2000 to be the 100%, what is 2200? well, 2200 is just 100% + 10%, namely 110%, and if we change that percent format to a decimal, we simply divide it by 100, thus
.
so, 1.1 is the decimal number we multiply a term to get the next term, namely 1.1 is the common ratio.

This is false, because the equation is then 12=2, which is incorrect.
Hope this helps!
