y-intercept = - 3


The equation of a line in #color(blue)"slope-intercept form"# is

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
