<span>Average speed = distance over time so here
Speed = (22 1/2) / (1/3) = 67 1/2 miles per hour</span>
The slope of the line is 2 whose equation is given by y = 2x.
The given equation is y = 2x
The general equation of the line is given by
y = mx +c where m is the slope and c is the intercept of the line.
The slope of line a line's steepness can be determined by looking at its slope. The slope is calculated mathematically as "rise over run."
The intercept of the line is a point on the y-axis known as an intercept is where the line's slope passes.
On Comparing the given equation with the general equation, we have:
m = slope = 2
Thus the slope of the line is 2.

Answer:
True
Step-by-step explanation:
Its true because a scatter plot (aka scatter chart, scatter graph) uses dots to represent values for two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables.
ANSWER
The discriminant is zero.
The given equation has one real root.
EXPLANATION
The given quadratic equation is:
We rewrite this in the form;
This means that,
a=-2, b= 8, c=-8
The discriminant is given by;
D=b² - 4ac
That is:
Therefore the discriminant is zero.
This tells us that the quadratic equation has one real root.
In order words, the given quadratic equation has a repeated real root.
We would find the midpoint by applying the formula for determining the midpoint of a segment which is expressed as
Midpoint = (x1 + x2)/2, (y1 + y2)/2
From the given points,
x1 = 4, y1 = - 5
x2 = 6, y2 = 1
Midpoint = (4 + 6)/2, (- 5 + 1)/2
Midpoint = 10/2, - 4/2
Midpoint = 5, - 2
