<u>Answer:</u> The slope of the line formed by these two points is 
<u>Step-by-step explanation:</u>
To calculate the slope, we use the formula:

For the coordinates given:

Putting values in above equation, we get:

Hence, the slope of the line formed from these two coordinates is 
Answer:
$24
Step-by-step explanation:
30X + 40
$24 IS THE RATE OF CHANGE
Answer:
(a) 2ab - a/b
(b) c² + d + 2cd
(c) c + c²
(d) Let x be the number that is 1 greater than b, then x = b + 1
Let y be the number twice as large as b, then y = 2b
Then the quotient of x and y is what we want. This is (b + 1)/2b
(e) pq - 3(p + q)
(f) The quotient of n² and n³ + 5, this is
n²/(n³ + 5)
