A student solved the following problem. 3/5 t + 7 = -8

3/5 t = -15

t = -9

Which of the following statements is true?

The solution is wrong, because the -15 should be -1.
The solution is wrong, because the -15 should be 1.
The solution is correct.
The solution is wrong, because the -9 should be -25.

B.the point lies directly on the regression

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
