Answer:
-1/2
Step-by-step explanation:
the slope of a line that is perpendicular to a given equation of a line, is the negative reciprocal of the original slope
Answer:
Yes,a similar formula is used to find all the products
Step-by-step explanation:
The formula applied in this case is;
(a+b)²= (a+b) (a+b)= a(a+b)+b(a+b) = a²+ab+ab+b²= a²+2ab+b²
In the first one;
In the second one;
⇒This is the same for the third and fourth product.

Step-by-step explanation:
C ,in the most parenthesis
1/3 is the slope. When you rearrange the equation to be in y=mx+b form, you would subtract 9 and divide by three. x divided by 3 is equal to 1/3 x, so that would be the slope
