Question

Write an equation of a line with the given slope and y-intercept.

m = –2, b = 4


y = 4x – 2





y = –2x + 4


y = –2x – 4

Answer 1

To write the equation of a line using the slope-intercept form, which is given by the formula \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept:

Given:
- Slope (\( m \)) = -2
- Y-intercept (\( b \)) = 4

Substituting these values into the formula, we get:

\[
y = -2x + 4
\]

So, the correct equation of the line is:

**y = –2x + 4**
