If a line has slope (-4) and (y)-intercept (9), which equation is correct?

Answer and explanation

Correct answer: (y=-4x+9)

The slope-intercept form of a straight-line equation is \(y=mx+b\). Here, \(m\) represents the slope and \(b\) represents the \(y\)-intercept. The question gives slope \(-4\), so the coefficient of \(x\) must be \(-4\). It also gives a \(y\)-intercept of 9, so the constant term must be 9. Substituting these two values into the standard form identifies the equation.

Using \(m=-4\) and \(b=9\), we obtain \(y=-4x+9\). This is option D. The equation \(y=4x+9\) has the correct intercept but the wrong slope because its slope is positive. The other choices either interchange the two numbers or change their signs, so they do not satisfy both given properties.
