Find the slope of the line passing through the points (-4,7) and (2,-9)

Ira Lisetskai [31]

Answer: The slope is -8/3

Step-by-step explanation: Use the slope formula y2-y1/x2-x1

so -9-7/2-(-4) = -16/6 which can be divided by 2 to get -8/3

What happens when x is a very small negative number?

marshall27 [118]

With this line, we see that when x is a small negative number, F(x) is a very large negative number, or B.

Remember that F(x) is the same as y. And looking at the pattern of the line, the greater the negative x is, the smaller the negative y is.

Find the terminal point on the unit circle determined by pi radians.

svet-max [94.6K]

Answer:

Terminal points

$(x,y) = (\frac{1}{\sqrt{2} }) , (\frac{-1}{\sqrt{2} })$

Step-by-step explanation:

According to the question, it is provided that

$\theta = \frac{7\pi}{4}$

Now

$x = 1. cos (\frac{7\pi}{4})\\\\ = cos (2\pi - \frac{\pi}{4})\\\\= cos \frac{\pi}{4} \\\\= \frac{1}{\sqrt{2} }$

$y = 1. sin (\frac{7\pi}{4})\\\\ = sin (2\pi - \frac{\pi}{4})\\\\= -sin \frac{\pi}{4} \\\\= \frac{-1}{\sqrt{2} }$

Now

$(x,y) = (\frac{1}{\sqrt{2} }) , (\frac{-1}{\sqrt{2} })$

These two represents the terminal points

We simply applied the above equations and then equate these two equations to determine the terminal points and therefore the same is to be considered

It could be figure out by using the x and y points

Therefore the two shows the terminal points

Select the equation of the line that passes through the point (5,7) and is perpendicular to the x = 4

Kamila [148]

Answer:

y= -1*x +12

Step-by-step explanation:

x=4 is a function that always has the value 4 for the x-axis, no matter y variable, this a vertical function.

Perpendicular Lines are those with the following condition:

y=a*x+b (1)

y=c*x+d (2)

Where a and c are the respective slope

If These two lines are perpendicular, then

a=- 1/c

Using those principles we have that the slope for our needed line has to be -1, since the slope for the first line is 1 (the coefficient of x is 1, in the line x=4)

Lets use the given point (5,7) in the equation (2)

7=-1 * 5 + d

resulting d=12

so, our equation for the line is y= -1*x +12
