The coordinates of the school is (8,2)
Let's round the numbers into perfect roots. So 23 rounded would be 25, because the square root of 25 is 5, and 47 rounded is 49, because the root of 49 is 7. So 7-5=2. That would be the best approximation for this question.
If the x between 5 and 2 is a letter then the answer is -21
If it’s a multiplication sign then it’s 19
Answer:
y = -3x + 2
Step-by-step explanation:
To find the slope of an equation you can do (y2-y1)/(x2-x1). Plug the values in from the equation and you get (-1+7)/(1-3), or 6/-2. This means the slope is -3. Then you plug the values of y and x into an equation y = -3x + b, and you get -1 = (-3)1 + b. Solve for b. -1 = -3 + b, (add 3 to each side) 2 = b. Then plug b back into your equation and you get y = -3x + 2
To find the percentage,here's what we can do:

The percentage would then be:
=63/420×100%
=3/20×100%
=0.15×100%
=15%
Therefore the answer is 15%.
Hope it helps!
