Answer:
(0,-7)
Step-by-step explanation:
In this question, we need to find an ordered pair of (x,y)
First we need to solve the equation for Y. It will be:
y-3=5(x-2)
y=5x-10 +3
y= 5x -7
Then, using the equation you can find the value of y using the value of x. If x= 0 the calculation will be
y= 5x-7
y= 5(0) - 7
y=-7
The ordered pair will be: (0,-7)
An Easy Way to do this is to write out the sample space.
5 10
5 25
10 5
10 25
25 5
25 10
Then, check which ones, add to over 20
5 25
10 25
25 5
25 10
Therefore, it's 4/6 or 2/3
