HELP NOW!!! 20 POINTS AND URGENTLY NEEDED!!!!!!!!!!!!!!

Lunna [17]

So basically here is the answer mate!

2x + 7y = 3-------------------------(substitute x's value here, i.e., x = -4y)

2( -4y ) + 7y = 3

-8y + 7y = 3

-1y = 3

y = -3------------------------( 1 )

Since x = -4y

= -4 ( -3 ) --------------------------( since we found the value of y)

= 12

Here is the answer for x = 12 , y = -3

Mark my anwer as the brainliest please ! :)

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).

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