Question 182177
<font face="Times New Roman" size="+2">


The <i>y</i>-intercept is the point where the graph of the equation intersects the <i>y</i>-axis.  Every point on the <i>y</i>-axis has a characteristic in common, namely the <i>x</i>-coordinate is 0.  So, all <i>y</i>-intercepts are in the form (0, b) where <i>b</i> is the value of <i>y</i> when <i>x</i> = 0.


Similarly, the <i>x</i>-intercept is an ordered pair of the form (a, 0) where <i>a</i> is the value of <i>x</i> when <i>y</i> = 0.


For example, in your first problem, when <i>x</i> = 0:


*[tex \LARGE \text{          }\math y = 3(0) - 6 = -6]


Therefore the <i>y</i>-intercept is (0, -6)


You should be able to to the rest.
