Determine the intercepts of the line. y=−2x−21

yuradex [85]

Hi there!

Let's first determine the x-intercept. When dealing with an x-intercept we must realise the y-coordinates equal 0.

$y = - 2x - 21 \\ y = 0 \\ \\ - 2x - 21 = 0$
Add 21 to both sides.

$- 2x = 21$
Divide both sides by -2.

$x = \frac{21}{2} = 10 \frac{1}{2}$
Therefore, the x-intercept is the point (10 1/2; 0).

--------------------------------------
Now let's continue with the y-intercept, which is easier. When dealing with an y-intercept we must realise the x-coordinates equal 0.

$y = - 2x - 21 \\ x = 0 \\ \\ y = - 2 \times 0 - 21 = - 21$
Therefore, the y-intercept is the point (0; -21).

The graph shows the linear parent function.Y5-55----Which statement best describes the function?

Vikki [24]

From the picture, we have the graph of the linear parent function f(x) = x.

We have the following statements as descriptions of the function:

A. The function is negative when x < 0.

From the graph, we see that the function takes negative values for x < 0. This statement is true.

B. The function is negative when x < 0 and also when x > 0.

The first part of this statement is true, but the second is not because that we see that the function takes positives values for x > 0. So this statement is false.

C. The function is never negative.

If we see the graph, the function is negative when x < 0. So this statement is false.

D. The function is negative when x > 0.

Again, seeing the graph we note that the function takes positive values for x > 0. So this statement is false.

So the only statement that it is true, is option A.
