Question

If A = {(x, y): (2, -2), (4, -1), (6, 0), . . .}, complete the rule for set A.

y=
A.) 1/2x - 3
B.)-1/2x + 3
C.)-1/2x - 1

Answer 1

slope is \(-\frac{1}{2}\) because it is right two units, down 1
so you can ignore the first one

then check to see which of the last two work
for example, if \(x=6\) which one gives you 0?

Answer 2

so the answer is B
