Want Brainliest? Get this correct Does this graph show a function? Explain how you know. A.No; there are y-values that have more than one x-value. B.No; the graph fails the vertical line test. C.Yes; the graph passes the vertical line test. D.Yes; there are no y-values that have more than one x-value.

Option (B)

Step-by-step explanation:

To test any relation whether it's a function or not we use the vertical line test.

For any value of x, if we find two values of y lying on the vertical line, graph will not represent a function.

We can see in the given graph,

If we draw a vertical line x = 2, we find two y-values (y = -1, 1) lying on this line.

Therefore, all parabolas don't represent a function.

Option (B) will be the answer.

the answer is d

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
