A graph of the equation shows the appropriate choice to be
C. 2
_____
If you would rather, you can look at the value of the discriminant. For the equation y = ax²+bx+c, the discriminant (d) is
d = b²-4ac
For your equation, this evaluates to
d = (-8)²-4(2)(5) = 64 -40 = 24
When the discriminant is positive, the function has two real roots (2 x-intercepts). When it is zero, there is only one x-intercept, and when it is negative, there are none (the roots are complex).

The slope of the line that passes through the following points is undefined
<em><u>Solution:</u></em>
Given that, We have to find the slope of line passing through two points
Given points are (-1, 5) and (-1, 6)
<em><u>The slope of line is given by formula:</u></em>
From given,
<em><u>Substituting the values we get,</u></em>
Thus the slope is undefined
The best type of chart for quickly deriving the mode of a sample data is called the Stem-and-Leaf Plot.
<h3>What is a Stem-and-Leap Plot?</h3>
In statistics, the Stem-and-Leaf Plot is an easy-to-make easy-to-read kind of graph that is derived from the table holding the sample data.
The Box-and-Whisker Plot on the other hand is best for visually depicting the five-number summary of any set of data, which are:
- Minimum
- First Quartile
- Median (Second Quartile)
- Third Quartile; and
- Maximum.
It is to be noted that referenced plots are not indicated hence, the general answer.
