The point-slope form:
We have the points (3, -4) and (5, 1). Substitute:
The standard form:
<em>multiply both sides by 2</em>
<em>use distributive property</em>
<em>subtract 2y from both sides</em>
<em>subtract 15 from both sides</em>
Let f(x)=0.
Using the zero-factor property, equate each factor to 0 and then solve for x.
Thus, the zeros of the given function are 6 and -5.
The zeros are the x-coordinate where the graph touches the x-axis.
Thus, the x-coordinates of where the graph touches the x-axis are -5, and 6.
