Question: 1 / 400

What is the slope-intercept form of the line with a slope of 1 and y-intercept of -1?

y = x + 1

y = x - 1

To find the slope-intercept form of a line, we use the formula \(y = mx + b\), where \(m\) represents the slope and \(b\) is the y-intercept. In this case, the slope is 1 and the y-intercept is -1.

Substituting the given values into the slope-intercept formula, we have:

\[

y = 1x - 1

\]

This can be simplified to:

\[

y = x - 1

\]

This equation clearly reflects a line that rises at a 45-degree angle (since the slope is 1) and crosses the y-axis at -1. Each unit you move to the right on the x-axis, the line moves up one unit on the y-axis, aligning with a slope of 1.

Thus, the correct representation of the line with these specific characteristics is indeed \(y = x - 1\).
