What is the equation of a line passing through \((0,4)\) with slope \(-2\)?

1. y = -2x + 4
2. y = 2x - 4
3. y = -2x - 4
4. y = 2x + 4

Correct answer: y = -2x + 4

Solution

A line with slope \(m\) and y-intercept \(c\) has equation \(y = mx + c\). Here, slope = -2 and the line passes through \((0,4)\), so \(c = 4\).
