Answer:
y - 3 = -1/2(x-1)
Step-by-step explanation:
Given the coordinates (1, 3) and (5,1). The point slope form is expressed as;
y - y0 = m(x-x0)
m is the slope
(x0, y0) is the required point
Get the slope
m = 1-3/5-1
m = -2/4
m = -1/2
Using the point (1,3), substitute
y - 3 = -1/2(x-1)
2(y-3) = -(x-1)
Hence the required equation is y - 3 = -1/2(x-1)

Answer:
A) 

Step-by-step explanation:
When given a balanced scale (represented by a hanger in this image), the sum of the values on one side equals the value on the other side. Thus, the equation that this hanger represents is the following:

Use inverse operations to solve this equation,



Answer:
I got C because A and B are too small for the standard division to be a mean of 80% and the number also cannot be 50% or higher because it could bring the median lower and or higher
Answer:
-66.66666667 percent
Step-by-step explanation:
Where: 57 is the old value and 19 is the new value. In this case we have a negative change (decrease) of -66.66666667 percent because the new value is smaller than the old value.
