# What is the y-intercept of the line represented by the equation y = 2x - 3?

Jun 29, 2016

y-intercept = - 3

#### Explanation:

The equation of a line in $\textcolor{b l u e}{\text{slope-intercept form}}$ is

$\textcolor{red}{| \overline{\underline{\textcolor{w h i t e}{\frac{a}{a}} \textcolor{b l a c k}{y = m x + b} \textcolor{w h i t e}{\frac{a}{a}} |}}}$
where m represents the slope and b, the y-intercept.

The advantage to having the equation in this form is that m and b can be extracted 'easily'.

the equation here : y = 2x - 3 is in this form and by comparison can obtain that

y-intercept = - 3
