The slope of the line is m=3/4. One point is (x, 2) and (3,-4)<br> Find X<br><br> Please helppppp
irina [24]

Answer:

x = 11

Step-by-step explanation:

Given that,

The slope of the line, m = 3/4

First point = (x,2)

Another point = (3,-4)

We need to find the value of x.

The slope of a line is given by the formula as follows :

m=\dfrac{y_2-y_1}{x_2-x_1}

Put x₁ = x, y₁ = 2, x₂ = 3, y₂ =-4 and m = 3/4

Put all the values,

\dfrac{3}{4}=\dfrac{-4-2}{3-x}\\\\3(3-x)=4(-6)\\\\9-3x=-24\\\\9+24=3x\\\\33=3x\\\\x=11

So, the value of x is 11.

Write -33/12 as a mixed number in reduced form. -2 -1 -2 -2
AysviL [449]
-33/12. Lets forget the negative symbol.

12 goes into 33, 2 times with 9 remaining.

So now get the negative sign back.

It will be -2 9/12 but you can reduce that to -2 3/4.

Hope this helps :)
