what is the equation in point-slope form of a line that passes through the points (7, -8) and (-4, 6)?
Marizza181 [45]

<u>Answer</u>

y - 6 = -14/11(x + 4)


<u>Explanation</u>

slope = (change in y)/ (change in x)

          = (6 - -8) / (-4 - 7)

         = 14/-11

         = -14/11

Equation

-14/11 = y - 6)/(x - -4)

-14/11 = (y - 6)/(x + 4)

-14(x + 4) = 11(y - 6)

y - 6 = -14/11(x + 4)


The answer is the third one.

Jason paints 1/4 of the area of his living room walls, w, on Monday. On Tuesday, he paints twice as much as he painted on Monday
AlekseyPX

Answer:

Step-by-step explanation:

Let us assume that the total area of the wall to be painted is w.

Then Jason painted an area of  (1/4)w on Monday

And he painted (2)(1/4)w on Tuesday

So to find the unpainted area, we just take the whole wall area to be painted (which is w) and subtract out the amounts painted on Monday and Tuesday, which are shown above.

So the unpainted area (U) would be shown by the following expression:

U = w - (1/4)w - (2)(1/4)w

We can simplify this expression by factoring out w

U = w(1 - 1/4 - 1/2)

U = w (1/4) or w/4

So all Jason needs to do is paint as much of the wall as he did on Monday, and he will be done!
