I need help with the equation!

Yo faith!
Question 3: Use the equation y= mx + b where m equals slope or the rate of change and b equals the y-intercept.
We already have b, which is 100. The reason why it's 100 is because the y-intercept is where the line crosses directly over the y-intercept. To do so, the x-value must be 0.
Thus y = mx + 100
The slope/ROC can easily be said to be -10 as the x value changes by adding 1 and the y value changes by subtracting 10. However, let's just presume that we didn't know this and couldn't use mental math.
To calculate the slope, we'll use the formula
Take two points and insert them. I've chosen them for you:
1. (1,90)
2. (2,80)
⇒
⇒ -10
Therefore your equation, Faith, is y = -10x + 100
Question 1 of C:
Graph - If the ordered-pair points formulate a straight line.
Table - Constant rate of change/slope for the x and y values.
Equation - No exponents are present.
Question 2 of C: Not sure what ''previous problems'' are given that they are not supplied.

Answer:
Ordering of objects from heaviest to lightest are ⇒ <u> school bus weight 9 tons, elephant 5,500 kilograms, horse 1,100 pounds and grand piano 15,840 ounces.</u>
Step-by-step explanation:
Given:
School bus weight = 9 tons.
Horse = 1,100 pounds.
Elephant = 5,500 kilograms.
Grand piano = 15,840 ounces.
Now, order these objects from heaviest to lightest.
So, we need to take a common unit to order the items:
Thus, we take pounds as a common unit.
16 ounces = 1 pound.
1 kilogram = 2.2 pounds.
1 ton = 2,000 pounds.
Then, we calculate the weight of all items in pounds:
School bus 9 tons
Horse 1100 pounds
Elephant 5500 kilograms
Grand piano 15840 ounces
According to question:
Ordering from heaviest to lightest:
<em>School bus = 18000 pounds, elephant = 12100 pounds, horse = 1100 pounds and grand piano = 990 pounds.</em>
Therefore, ordering of objects from heaviest to lightest are ⇒ school bus weight 9 tons, elephant 5,500 kilograms, horse 1,100 pounds and grand piano 15,840 ounces.
