Plot the points on a graph. Connect the dots into a triangle. See that the height of the triangle is from y=5 down to y=1. So the height is 4 units.
 Area of a triangle: A = (1/2)BH 
You need to find the length of the base. Which is from point (-4,1) to (0,1). You can use the distance formula r just see from the graph that the base is 4 units. 
A = (1/2)(4)(4) 
A = 8 
** Distance formula fyi
d² = (X-x)² + (Y-y)²
with points (X,Y) and (x,y)

Answer:
(A)20%, 20%, 20%, 20%, 20%
Step-by-step explanation:
We are told that 20% of the M&M's produced by the Mars Corporation are Orange in color. If 5 students take a random sample of 50 M&M's, the most plausible percentage of orange candies that will be obtained is:
20%, 20%, 20%, 20%, 20%
This is as a result of the fact that in research experiments, a sample is a representation of the whole. Any result which holds for a random sample should hold for the total population and vice versa.
 
        
             
        
        
        
The slope is 3/4. you need to find the change of y over the change of x.
