Line through (-4,0) and (0,-2)

Slope is change in y over change in x

m = (-2 - 0)/(0 - -4) = -2/4 = -1/2

Answer: -2/4 = -1/2, second choice

Find the slope of the line. On a coordinate plane, a line goes through (0, negative 2) and (2, negative 4). a. -1 c. -2 b. 2 d.

RSB [31]

Answer:

m = -1 (answer (a))

Step-by-step explanation:

Recall that the slope of a straight line is m = rise / run.

As we go from the point (0, -2) to the point (2, -4), we see an increase of 2 in x and a decrease of 2 in y.

Thus, the slope of this line is m = rise / run = 2/(-2), or m = -1 (answer (a))

Find the slope of each line and then determine if the lines are parallel, perpendicular or neither. If a value is not an integer

Aleonysh [2.5K]

As given by the question

There are given that the point of two-line

$\begin{gathered} (1,\text{ 7) and (5, 5)} \\ (-1,\text{ -3) and (1, 1)} \end{gathered}$

Now,

From the condition of a parallel and perpendicular line

If the slopes are equal then the lines are parallel

If the slopes are negative reciprocal then the lines are perpendicular

If the slopes are neither of the above are true then lines are neither

Then,

First, find the slope of both of line

So,

For first-line, from the formula of slope

$\begin{gathered} m_1=\frac{y_2-y_1}{x_2-x_1} \\ m_1=\frac{5_{}-7_{}}{5_{}-1_{}} \\ m_1=-\frac{2}{4} \\ m_1=-\frac{1}{2} \end{gathered}$

Now,

For second-line,

$\begin{gathered} m_1=\frac{y_2-y_1}{x_2-x_1} \\ m_1=\frac{1_{}-(-3)_{}}{1-(-1)_{}} \\ m_1=\frac{4}{2} \\ m_1=2 \end{gathered}$

The given result of the slope is negative reciprocal because

$\begin{gathered} -\frac{1}{2}=-(-\frac{2}{1}) \\ -\frac{1}{2}=2 \end{gathered}$

Hence, the slope of line1 is -1/2, and slope of line2 is 2 and the lines are perpendicular.

Please help me with this question

mash [69]

Answer:

angle AOD = 90⁰

BOD = 3x⁰

90⁰+3x⁰ = 180⁰( being straight angle)

3x = 180⁰-90⁰

3x = 90⁰

x = 90⁰/3

x = 30⁰

now

y⁰+139⁰ = 180⁰(being straight angle)

y⁰ = 180⁰-139⁰

y⁰ = 41⁰

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Answer:

a = 5.

Step-by-step explanation:

The graph here is a probability density graph. What will represent $P(X\le a)$ on the graph?

$P(X\le a)$ is the area

between the graph and the x-axis,
to the left of $a$ .

The area under the graph between 0 and 9 is a trapezoid. Consider the trapezoid in three slices from left to right:

A right triangle of area $\displaystyle \frac{1}{2}\times 0.2\times 4 = 0.4$ ,
A rectangle of area $0.2 \times (5 - 4) = 0.2$ , and
Another right triangle of area $\displaystyle \frac{1}{2} \times 0.2 \times (9 - 5) = 0.4$ .

The area of the leftmost triangle plus that of the rectangle is exactly 0.6. In other words, the area to the left of $a = 5$ between the graph and the x-axis is $0.6$ . $P(X \le 5) = 0.6$ . $a = 5$ .

As a side note $a = 5$ shall be the only answer to this question since the area under the graph to the left of $a$ can only increase or stay constant but not decrease as the value of $a$ increases.
