Answer:
B; (2,-4)
Step-by-step explanation:
The general equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
So from the question, when we look at the given equation, its slope is -1/2
mathematically, when two lines are perpendicular, the product of their slopes is -1
thus;
m1 * m2 = -1
m2 * -1/2 = -1
-m2 = -2
m2 = 2
The general equation form is;
y-y1 = m(x-x1)
where (x1,y1) = (4,0)
y-0 = 2(x-4)
y = 2x - 8
So, now we look at the point that will work for this equation
For the line that will work, if we substitute its x-value, we get the y-value
Let us take a look at option B
y = 2(2) -8 = 4-8 = -4
we can see that (2,-4) works
Answer:
x = 12
Step-by-step explanation:

The first thing you should do is observe the behavior of the graph.
It is not linear because the rate of change is not constant.
It is not exponential because the rate of change does not grow or decrease rapidly.
For this case the best regression model is a model of the form:

Where,
a <0: This is because we have a parabola that opens downwards.
Therefore, the best regression model is quadratic.
Answer:
By visual inspection, the best-fitting regression model for the data plot is:
A. Quadratic
