How to graph this! Thank you

Step-by-step explanation:

Yay graphs!!!!!!

Okay so as you should know, the structure of a linear equation is y = mx + b.

B is the y-intercept

so the first thing to do is mark the coordinates (0,1) as the y-intercept

Now the slope is 1/4 x

this is also known as rise/run

A simpler way to do that is from (0,1) move up 1 and over four and place a point there

The coordinate should be (4,1)

Then draw a line through the two points

A number cubed is rolled. What is the probability that a one or six will be rolled

son4ous [18]

Answer: 1/3

Step-by-step explanation: Since there are six sides to a number cube, the total number of outcomes will be 6.

Since there are 2 favorable outcomes, rolling a 1 or a 6,

the probability of rolling a 1 or a 6 is 2/6 which reduces to 1/3.

In the diagram below, assume that all points are given in rectangular coordinates. Determine the polar coordinates for each poin

Korolek [52]

Step-by-step explanation:

We have cartisean points. We are trying to find polar points.

We can find r by applying the pythagorean theorem to the x value and y values.

$r {}^{2} = {x}^{2} + {y}^{2}$

And to find theta, notice how a right triangle is created if we draw the base(the x value) and the height(y value). We also just found our r( hypotenuse) so ignore that. We know the opposite side and the adjacent side originally. so we can use the tangent function.

$\tan(x) = \frac{y}{x}$
