What is the equation in point slope form of the line that passes through the point (−1, −3) and has a slope of 4?

Dmitry_Shevchenko [17]

The point-slope form:

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

We have the slope m = 4 and the point (-1, -3). Substitute:

$y-(-3)=4(x-(-1))\\\\\boxed{y+3=4(x+1)}$

Aliun [14]

Answer:

The correct option is C) Both of the above.

Step-by-step explanation:

Consider the provided statement.

First understand the meaning of Confidence level.

Confidence level refers to the percentage of likelihood, or assurance, that when you draw a random sample several times, the confidence interval will contain the true population variable.

99% confidence means We are 99% sure that most of these confidence intervals contain the true parameter of the population.

Therefore, both the statement are correct.

Hence, the correct option is C) Both of the above.

Select the correct answer.<br> √3<br> 1,53<br> If the point<br> 3 is on the unit circle, what is x?

emmasim [6.3K]

If the point ( x, √3/ 3) is on the unit circle, then the value of x will be √2/ 3. The correct option is D.

<h3>What is the equation of the circle with radius r units, centered at (x,y)?</h3>

If a circle O has a radius of r units length and it has got its center positioned at (h, k) point of the coordinate plane,

then, its equation is given as:

$(x-h)^2 + (y-k)^2 = r^2$

The equation of unit circle is

$(x-h)^2 + (y-k)^2 = 1\\\\x^2 + \dfrac{\sqrt{3} }{3}^2 = 1\\\\x^2 + \dfrac{1 }{3} = 1\\\\\\x^2 = 1 - \dfrac{1 }{3} \\\\x^2 = 2/3\\$

Thus, x = √2/ 3

If the point ( x, √3/ 3) is on the unit circle, then the value of x will be √2/ 3.

The correct option is D.
