if an ordered pair is a solution, it should satisfy the equation.
see the first option
, if you put $x=4$ and $y=12$
you'll get $12=12$ which is true.
now the last option, $y=8-x$ put $x=4$ and $y=12$
$12=8-4\implies 12\ne4$ thus it is not a solution.
So option 4 is correct
First analyze your question. Barbara has a goal to read 45 minutes every day. If she meets her goal, how many minutes will she have read in 360 days?

Answer:
(-4,-5)
Step-by-step explanation:
The slope of the line passing through (3,5) and (-2,1) would be:
It would be:
y2 - y1 / 2 and x2 - x1 / 2
= 1 -5 / 2 and -2 -3 /2
= -4/2 and -5/2
= (-4,-5)
Hope this helped :3
