The line (y=4x+b) has (y)-intercept (11). Which equation is correct?
Answer and explanation
Correct answer: \(y=4x+11\)
In the form \(y=4x+b\), the constant term \(b\) is the \(y\)-intercept. Since the \(y\)-intercept is 11, substituting \(b=11\) gives \(y=4x+11\). Option B has intercept \(-11\), while option D changes the slope to \(-4\). Exam tip: in \(y=mx+c\), identify \(c\) directly as the \(y\)-intercept.
