make it a function of y respect to x
Yes. If you put it in the form: \(\sf \color{red}{y=mx+b}\) You will see
ok so it is increasing y=-2x+1

what makes you say it's increasing?
sorry decreasing
okay right!
god help us it is not your fault, but \[-y - 2 = x + 1\] is not a function at all it is an equation
It's a linear function, no?
I have it in my homework it says if it is increasing or decreasing
no it is not a linear "function" it is an equation for a line thus beginning the long confusion between the concept of "function" and "equation" it is not your fault just bad math teachers
anyway what they want you to do is solve for \(y\) \[-y - 2 = x + 1\] \[-y=x+3\] \[y=-x-3\]
but is it increasing or decreasing
and then say "since the slope is negative, it is decreasing
\[y=-x-3\\y=mx+b\] \[m=-1\] so it is decreasing
ok thank you. was not sure
yw sorry you have such a crappy book
y = -5x + 4 so this one is increasing right
i meant decreasing sorry didnt see the -
yeah, decreasing
k thanks
