Question

Is the (4, 1) a solution to the equation y = -x + 3?

I honestly have no idea what this means. Does y = 4 and 1 = -x? If not then the answer should be no since (4, 1) is part of a graph

Answer 1

In an ordered pair such as (4,1), the first number is always the x and the second number is always the y , that tells us
that x = 4 and y = 1

so subbing that into y = -x + 1 ....

is 1 = -4 + 3 ??? , clearly not

so (4,1) is NOT a solution for the given equation.

Thank you so much
