The slope intercept form of a line
is
y = mx + b.
Where m is the slope and b is the
y-intercept.
The y-intercept is the point where the line crosses the y-axis.
In the example to the right, the line crosses the y-axis at point
(0,3). Therefore b = 3. The slope is 2.The slope intercept equation
is
y = 2x + 3.
