The points (0, 3) and (4, -1) are on the graph of y = -x + 3.
I have a site that I use a lot that is perfect for problems like these. It's called Desmos.com. It's basically a free online graphing calculator that is super helpful for most problems relating to graphs.
Answer:
umm what do you mean can like you explain
Answer:
There is no solution
Step-by-step explanation:
The slopes are the same and the y-intercepts are different.
Think of this as the slope as an amount you get per week and y-intercept as how much you start off with. You have a friend that starts off with 10 dollars and gains 5 dollars every week and you start off with 5 dollars and gains 5 dollars every week. Will you ever catch up to your friend if you and your friend don't spend any money? I don't think so. The solution to a set of equations is when both equations have the same y value with the same x value.

Ana has 4 coins with different values(5, 10, 20, 50) and you are asked to find how many different sums they can make. You can see every value as a separate combination and multiply it.
There is 1 coin for every value and it can be either used or not used, so there are two probabilities for each coin value. The calculation would be:
C(2,1)= 2!/1!= 2
There are 4 values of coins, so the total probability would be:
4 * C(2,1)= 4*2=8 ways
