Is (-1 -1) a solution of y 3x 2?

Answer 1

The mathematical symbols did not appear so I am assuming that your question is if the point (-1,-1) is a solution of y = 3x + 2, in that case, substitute -1 for y and -1 for x and you get

-1 = 3(-1) + 2 or

-1 = -3 + 2 or

-1 = -1

Thus if I assumed the question correctly, then -1,-1 is a solution to y = 3x + 2

Answer 2

Symbols, such as plus and equal signs, get lost in questions (and some symbols in the answers, as well). In any case, just replace "x" with the first number, and "y" with the second number, then evaluate and see whether it's equal.
