Find the slope of the line below. Enter your answer as a fraction of
Levart [38]

Answer:

  • \boxed{\sf{\dfrac{3}{10}}}

Step-by-step explanation:

Use the slope formula.

<h3 /><h3>What is a slope?</h3>

Slope is a surface with one end higher than the other and with no steps. It proceeds at an angle. The path sloped down to the beach.

So, the property possessed by a line or surface that departs from the horizontal.

<u>Slope formula:</u>

\longrightarrow \sf{\dfrac{y_2-y_1}{x_2-x_1} }

(-6,-2) (4,1)

  • y₂=1
  • y₁=(-2)
  • x₂=4
  • x₁=(-6)

<u>Rewrite the problem down.</u>

\sf{\dfrac{1-\left(-2\right)}{4-\left(-6\right)}}

<u>Solve.</u>

1-(-2)=1+2

<u>Add.</u>

1+2=3

4-(-6)=4+6

4+6=10

\boxed{\sf{\frac{3}{10} }}

Therefore, the slope is 3/10, which is our answer.

Ellason wants to solve the following system using the elimination method: 5x + 2y = 30 x + y = 8 What number should the equation
Zinaida [17]
 - 2 because we obtain : - 2x - 2y = - 16 ;
We solve the system:
5x + 2y = 30
-2x - 2y = -16
_____________(+)
3x /       = 14;
x = 14/3;
y = 8 - 14/3;
y = 24/3 -14/3;
y = 10/3;

The solution of the system is ( 14/3 ; 10/3 )
