2x2-6x-11 ( the second two is above the x)
Answer:
Option C i.e. y = 1/2x + 5 is the correct option.
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
Given the points
A(4, 7)
B(-4, 3)
Determining the slope between A and B
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [3 - 7] / [-4 - 4]
= -4 / -8
= 4/8
= 1/2
Thus, the slope of the line = m = 1/2
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 5
Thus, the y-intercept b = 5
now substituting m = 1/2 and b = 5 in the slope-intercept form
y = mx+b
y = 1/2x + 5
Therefore, the equation of line in the graph is:
y = 1/2x + 5
Thus, option C i.e. y = 1/2x + 5 is the correct option.
From my knowledge, I would use the vertical line test instead of the horizontal line test. The vertical line test checks if something is a function, and the horizontal line test checks if an inverse function exists. (Correct me if I'm wrong, I haven't used this in a while.)
If I use the vertical line test:
A would fail because it intersects the vertical line more than once.
B would fail because the ellipse would intersect the vertical line more than once.
I can't see C too clearly, but from what I can make out of it, it doesn't pass the vertical line test because there are 2(?) lines and it intersects the vertical line more than once.
D passes the vertical line test because the parabola only intersects the vertical line at one point.
Hope I helped :)
