Answer:

D or last one

Step-by-step explanation:

Verify the graphs by the vertical line test.

If a vertical line crosses the graph at two or more points, then it is not a function.

We can see the first 3 graphs pass the test but the last one fails.

So the last graph (bottom right picture) doesn't represent a function.

Answer:

The point where the line crosses the x-axis is called the [x-intercept].

Which equation shows the relationship in the table below X 3, 5, 8, 11 Y 7 ,11, 17, 23 a y=2xb y=x+4 c y=2x+1 d y=2x+4

ladessa [460]

ANSWER

$c)\text{ }y=2x+1$

EXPLANATION

We want to find the equation for the relationship shown in the table.

The relationship shown in the table represents a linear relationship. The general form of a linear equation is:

$y=mx+b$

where m = slope

b = y-intercept

To find the slope of the equation, apply the formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

where (x1, y1) and (x2, y2) are two sets of values from the table.

Let us take (3, 7) and (5, 11) as (x1, y1) and (x2, y2)

Hence, the slope of the equation is:

$\begin{gathered} m=\frac{11-7}{5-3}=\frac{4}{2} \\ m=2 \end{gathered}$

Now, to find the equation of the line, apply the point-slope method:

$y-y_1=m(x-x_1)$

Therefore, the equation that shows the relationship in the table is:

$\begin{gathered} y-7=2(x-3) \\ y-7=2x-6 \\ y=2x-6+7 \\ y=2x+1 \end{gathered}$

The correct option is option C.
