# How do you write an equation of a line with slope -7/2 and y-intercept 3?

Nov 20, 2016

#### Explanation:

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

$y = m x + b$

where m is the slope and b is the y-intercept.

To write the equation of the desired line, one substitutes $- \frac{7}{2}$ for m and $3$ for b:

$y = - \frac{7}{2} x + 3$
