Slope Intercept Form
Y intercept The y-intercept is
the point where a line crosses the y axis.
At this point the value of x is 0.
Y intercept To find the y-
intercept, plug 0 in for x in the linear equation and solve for y.
y=3x-6 (0, -6)
Slope y=3x-6 To find the slope first
find 2 points. (2, 0) and (0, -6) Then substitute in and
solve

Slope Intercept FormTo graph y=3x-6
Plot (0, -6) then count slope Up 3 right 1 Connect your
points to make a line.
Writing an EquationWrite the equation of the line with slope 3/8
and y-intercept 5.
Use slope intercept form:
Substitute in for m and b
