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

Question

m = 1, b = 4

y = x + 4

y = 4x + 1

y = x – 4

y = –1x + 4

Answer 1

To write the equation of a line given the slope \( m \) and the y-intercept \( b \), you can use the slope-intercept form of a linear equation:

\[ y = mx + b \]

Given that \( m = 1 \) and \( b = 4 \), you can substitute these values into the equation:

\[ y = 1x + 4 \]

This simplifies to:

\[ y = x + 4 \]

Therefore, the correct equation of the line is:

y = x + 4.
