Answer:

No because of the 3xy term. For an equation to be considered linear there has to be one y value for every x value given

It is not a linear equation because if you graph it is not linear. Each term must be either a constant or a product of a constant, but, in this case, there are 2 variables so it makes it non-linear looking at from a algebraic point-of-view.

Hi there!

We are given two ordered pairs which are:

(0,0)
(5,4)

If you are curious how do I get these ordered pairs, they come from those two big circles or dots. x and y make relation and can be written as (x,y).

1. Find the slope

Yes, our first step is to find the slope of a graph if you want to find an equation. You may be curious how to find that right? No worries! We have got a special formula for you to find the slope!

$\large \boxed{m = \frac{y_2 - y_1}{x_2 - x_1} }$

Since we have two given points, we can substitute them in the formula.

$\large{m = \frac{4 - 0}{5 - 0} } \\ \large \boxed{m = \frac{4}{5} }$

2. Form an equation.

Since we have finally found, got or evaluated the slope. Next step is to find the y-intercept. Oh! Before we get to form an equation, do you know the slope-intercept form? We will be using that linear equation form since it is commonly used in the topic.

$\large \boxed{y = mx + b}$

Where m = slope and b = y-intercept. We substitute m = 4/5.

$\large{y = \frac{4}{5} x + b}$

Next thing to remember is that when the graph intersects an origin point, b-term or y-intercept would be 0. Therefore b = 0 since the graph intersects (0,0).

$\large \boxed{y = \frac{4}{5} x}$

3. Answer

Therefore the equation of the line is y = 4x/5.

1. set up the equation which makes these shapes equal, 1/2(2(x+1)) = 1x

2. solve, x+1=x, 1=0

3. since this is impossible, there is no solution and zero answers

You roll two dice. What is the probability you get a 2 and a number greater than 2?

abruzzese [7]

Hello!

You have to find the probability of getting a 2

This is a 1/6 chance

Then you have to find the chance of getting a number greater than 2

This is a 4/6 chance

To find the chance of these happening at the same time you multiply these together

1/6 * 4/6 = 1/9

There is a 1/9 chance

Hope this helps!
