Question

A line has a slope of
–
1 and a y-intercept of
–
20. Write its equation in slope-intercept form.
Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answer 1

The slope-intercept form of a line is given by the equation:

\[ y = mx + b \]

where \( m \) is the slope and \( b \) is the y-intercept.

In your case, the slope \( m \) is \( -1 \) and the y-intercept \( b \) is \( -20 \).

Substituting these values into the slope-intercept formula, we get:

\[ y = -1x - 20 \]

or

\[ y = -x - 20 \]

So, the equation of the line in slope-intercept form is:

\[ y = -x - 20 \]
