Find the slope of the line that passes through the points (3, 6) and (5, 3).
Temka [501]
(3,6)    (5,3)
(x1,y1)(x2,y2)

The slope equation is: y2-y1
                                 ---------
                                  x2-x1

Replace with numbers: 3-6/5-3

Minus 3 and 6 is equal to -3

Minus 5-3 is 2 

So the fraction is -3/2 (no need to divide because you can't simplify it)

So the slope is -3/2

For the equation you have to replace the letters by 0's 

3×0-2y=6
Times 3 and 0
0-2y=6
Now you want to get the y alone, so minus 0 from both sides 
   0-2y=6
  -0      -0

-2y=6

Divide -2y from the 6

-2y=6
----  ---
  -2   -2

y=3 

The y intercept is 3 with the slope of -3/2

PLs answer fast i need this questions answer
Mashutka [201]

Answer:

x=6

Step-by-step explanation:

Given equation:

x-\left(2x-\dfrac{3x-4}{7}\right)=\dfrac{4x-27}{3}-3

Expand the left side:

\implies x-2x+\dfrac{3x-4}{7}=\dfrac{4x-27}{3}-3

Let all terms on the left side have the same denominator of 7:

\implies \dfrac{7x}{7}-\dfrac{14x}{7}+\dfrac{3x-4}{7}=\dfrac{4x-27}{3}-3

Join the terms on the left side:

\implies \dfrac{7x-14x+3x-4}{7}=\dfrac{4x-27}{3}-3

\implies \dfrac{-4x-4}{7}=\dfrac{4x-27}{3}-3

Let all the terms on the right side have the same denominator of 3:

\implies \dfrac{-4x-4}{7}=\dfrac{4x-27}{3}-\dfrac{9}{3}

Join the terms on the right side:

\implies \dfrac{-4x-4}{7}=\dfrac{4x-27-9}{3}

\implies \dfrac{-4x-4}{7}=\dfrac{4x-36}{3}

Cross multiply:

\implies 3(-4x-4)=7(4x-36)

Expand:

\implies -12x-12=28x-252

Add 12x to both sides:

\implies -12=40x-252

Add 252 to both sides:

\implies 240=40x

Divide both sides by 40:

\implies 6=x

\implies x=6
