Answer:
No
Step-by-step explanation:
15/20 is reduced to 3/4. Not equal to 4/5
782 + 821 = 1,603
2x2 = 4
Step 1:
Find the difference between the two numbers.
$2.40-$1.44= $0.96
Step 2:
Divide by the original number.
$0.96/1.44= 0.667
Step 3:
Multiply by 100 to find percent increase.
0.667 * 100= 66.7% rounded to one decimal place or 67% rounded

I worked the problem by hand. First I used the equation y=mx+b to find the rule for the function. To find m which is the same as the slope you use the change in y divided by the change in x. Or the change in output divided by the change in input. The two points or coordinates used were (-2,-4) and (1,-1). Once you have the slope you use y=mx+b and substitude y by any value of y (-4 or -1) and m is the slope calculated and x would be the corresponding x to the y value used (if -4 was chosen for y then -2 would be used for x). This will be used to calculate b.
