Try to find two point that land squarely on clear points. I'll use (-4,5) and (0,4)
The point slope form of a line is: y=mx+b where m is the slope and b is the y-intercept.
m=(y2-y1)/(x2-x1)=(4-5)/(0--4)
m=-1/4 we know b is 4 because of the point (0,4), but just for the sake of clarity... so far we have m so our line right now is:
y=-x/4 +b now we can use any point to solve for b, I'll use (-4,5) again...
5=--4/4 +b
5=1+b
b=4 so the line that produces that graph is:
y=-x/4 + 4 or more neatly...
y=(16-x)/4
Answer:
$595.34
Step-by-step explanation:
Step one
given data
interest rate of 2.5%= 0.025
final amount= $690
time = 6 years
Required
Principal P
Step two
The compound interest formula is
![A= P(1+r)^t](https://tex.z-dn.net/?f=A%3D%20P%281%2Br%29%5Et)
substitute
![690=P(1+0.025)^6\\\\690=P(1.025)^6\\\\690=P1.159\\\\](https://tex.z-dn.net/?f=690%3DP%281%2B0.025%29%5E6%5C%5C%5C%5C690%3DP%281.025%29%5E6%5C%5C%5C%5C690%3DP1.159%5C%5C%5C%5C)
divide both sides by 1.159
P=690/1.159
P= $595.34
The data for relationship B is shown in this table.

A graph of the data is shown below.
It passes through (0,0).
Its slope is
(121.6 - 30.40) / (8 - 2) = 15.2
Therefore its equation is
y = 15.2x +0 = 15.2x
Answer: y = 15.2x
Answer:
Slope: 2
