Answer:
(3,5)
1/3
Step-by-step explanation:
The equation is already in point-slope form. Therefore, both the point and slope can easily be found in the equation. Point slope form looks like . In this the point is
and the slope is m. So, the x value is 3 and the y value is 5, making the coordinate (3,5). Finally, the slope is 1/3.
<h3>Answer: Choice A</h3>
It factors to (x - 0.9)(x + 0.9)
=================================================
Work Shown:
I used the difference of squares factoring rule. The order of the factors doesn't matter. So an alternative answer is (x+0.9)(x-0.9)
