Answer:
(-4,1)
Step-by-step explanation:
Point A is located at (−2, −6), and D is located at (−6, 8).
We need to find the midpoint of A and D
Mid point formula is 
Point A is (-2,-6) that is (x1,y1)
Point D is (-6,8) that is (x2, y2)
plug in the values in the formula
Mid point is (-4, 1)
The solution is (1,3). This is where the two lines intersect.
The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept. Since you are given the slope (0.5) and the y-intercept (3), all you have to do is substitute these given values into the equation. Substituting them in you get: y = 0.5x + 3, which is your answer.
The solution of your problem is shown on the picture below.
There was a
66 
% increase from Sari's sales from November to December.
To find the percentage increase in her sales, we must first find the amount her sales increased. We can do that by subtracting the greeting cards sold in November from the number of greeting cards sold in December. Substituting values and simplifying, we get that she sold 200 more greeting cards in December.
To find what percent increase this is, we must find what percent 200 is of the number of greeting cards sold in November. We can do this by dividing 200 by the number of cards sold in November (300), and then multiplying by 100 (to make it a percent). Doing this, we get
* 100 which gives us our answer of
66 %.
