Question

Determine the y-intercept of the following equation.
left parenthesis, minus, x, plus, 3, right parenthesis, left parenthesis, minus, x, minus, 1, right parenthesis, equals, y
(−x+3)(−x−1)=
y

Answer 1

To find the y-intercept of the equation \((−x+3)(−x−1) = y\), we need to set \(x = 0\) and solve for \(y\).

Substituting \(x = 0\):

\[
y = (−0 + 3)(−0 − 1)
\]
\[
y = (3)(-1)
\]
\[
y = -3
\]

Thus, the y-intercept of the equation is \(-3\). Therefore, the y-intercept is at the point \((0, -3)\).
