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

1 answer

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
