Answer:
y - intercept
Step-by-step explanation:
Some equations only require one point of the graph to write a equation for, like point-slope form.
y - y1 = m(x - x1)
(x1, y1) - A point.
However, for the most common equation form, which is slope-intercept form, you would need to find the slope and the y-intercept of the line to write a complete equation.
[tex]y=mx+b[/tex]
m - slope
b - y-intercept
