<h3><u>Question:</u></h3>
On a recent day, 8 euros were worth $9 and 24 euros were worth $27. Write an equation of the form y = kx to show the relationship between the number of euros and the value in dollars.
<h3><u>Answer:</u></h3>
y = 1.125x is the equation to show the relationship between the number of euros and the value in dollars.
<h3><u>Solution:</u></h3>
Given that On a recent day 8 euros were worth 9 dollars and 24 euros were worth 24 dollars
Let "y" be the value in dollars
Let "x" be the number of euros
We have to write a equation in form of y = kx
<em><u>8 euros were worth 9 dollars</u></em>
"k" is found as follows:


Therefore, equation of y = kx is given as:


To check the equation, use the another given value
24 euros were worth $27

Hence the equation y = 1.125x is correct
Let’s find the slope and y intercept
Slope: rate of change
Given points (0,5) and (2,0)
Slope: (y2-y1)/(x2-x1)
(0-5)/(2-0) = -5/2
Y intercept = (0,y) = (0,5)
Now into equation: y = mx + b
Y = -5/2x + 5
Get rid of fraction (multiply be 2)
2y = -5x + 10
Add 5x to both sides
2y + 5x = 10
Or 5x + 2y = 10
Solution: D. 5x + 2y = 10
Answer:
275 - 11=264
