Recognize that this matches the "slope-intercept" form
y = mx + b
where b = 0.
The y-intercept is zero. The graph of this equation passes through the origin.
The y-intercept is the value of y when x is zero.
Y = 9*0 = 0
y = mx + b
where b = 0.
The y-intercept is zero. The graph of this equation passes through the origin.
The y-intercept is the value of y when x is zero.
Y = 9*0 = 0
