If you do 75/100 you'll get your answer which is 18/25.
You need to solve this "system of linear equations." In other words, find a point (x,y) that satisfies both 4x-3y=17 and 2x-5y=-11.
Try solution by elimination. Multiply the 2nd equation by -2 to obtain -4x+5y=22. Add this result to the 1st equation. I'd suggest you write this out to see what is happening.
4x-3y=17
-4x+10y=22
----------------
7y=39. Solving for y, we get y=39/7 (a rather awkward fraction).
Now find x. To do this, substitute 39/7 for y in either of the given equations. Solve the resulting equation for x.
Write your solution in the form (x, y): ( ? , 39/7).

Step-by-step explanation:
Answer: The slope is the cost per muffin and the intercept of 3 is the delivery charge.
Step-by-step explanation:
I will assume that the graph has total cost in dollars for the y axis and number of muffins on the x axis. A slope of 2 means that y will increase by 2 for every 1 increase in x. That means that the price of a single muffin is $2.
The intercept of 3 at x = 0, means that there is an upfront (delivery) charge of $3. One muffin would cost $2 for the muffin plus $3 for the delivery, for a total of $5.
10 muffins would cost $20 for the muffins plus $3 for the delivery, for a total of $23.
