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.

Hello!
Lynne invested 35,000 into an account earning 4% annual interest compounded quarterly she makes no other deposits into the account and does not withdraw any money. What is the balance of Lynne's account in 5years
Data:
P = 35000
r = 4% = 0,04
n = 4
t = 5
P' = ?
I = ?
We have the following compound interest formula
So the new principal P' after 5 years is approximately $42,706.66.
Subtracting the original principal from this amount gives the amount of interest received:
