You can take any 2 points from the table and calculate the slope, as follows:
-2-(-4) 2
m = slope = ---------- = ------ = -1/5
-5 - 5 -10
The slope-intercept form is y = mx + b. You already know m (which is -1/5), and have several points from which to choose to obtain x and y. Let's use the given point (-2, -1).
Then -1 = (-1/5)(-2) + b, or -1 = 2/5 + b. Solve for b.
-5 = 2 + 5b, so 5b = -7, and b = -7/5.
The desired equation is y = (-1/5)x - 7/5.
Answer:
D
Step-by-step explanation:
Please look at the attached picture for full solution.
Method 1 is using the shoelace method to find the area of the rectangle. Shoelace method can be used to find the areas of any polygons given their coordinates. The coordinates have to be taken in an anticlockwise order and ending with the first coordinate.
Method 2 is making use of the distance formula of two points. The formula is as shown below:

Having found the distance of the length and breadth of the rectangle, you can now find its area since area of rectangle= length × breadth.
Answer: -2

Because it is
Jason's airplane flew the farthest. When you find a common denominator for all the fractions, 8 2/3 is the largest,
Sara = 8 6/12
Jason = 8 8/12,
Michael = 8 3/12,
Denise = 8 2/12,
