Answer:

y  - 4 =  - 4(x + 2)

Step-by-step explanation:

Point Slope Form is a algebraic formula when we know a pair of points and it

slope.

It can be represented by

y -   y_{1} = m(x + x  _{1})

where m is the slope and x 1 and y 1 are the points we know.

The coordinates we know are (-2,4) so we just plug it in.

We also know the slope of the line is rise/run. Look at point (-2,4). The next consecutive point before that is x intercept (-1,0). Let use the slope formula to find the slope

\frac{0 - 4}{ - 1 - ( - 2)}  =  \frac{ - 4}{1}  =  - 4

So the slope or m is -4. Plug this in and the coordinates into point slope formula.

y - 4 =  - 4(x   - ( - 2)

y - 4 =  - 4(x + 2)

That the answer.

Answer: y = -4x - 4

Step-by-step explanation:

Point slope form: y - y1 = m(x - x1)

Plug in y1 and x1, and m. M is the slope, x1 and y1 are the values for a coordinate. You don't need to plug anything in for y or x, just y1 and x1.

First, find the slope. To find the slope, use this "formula" : slope=\frac{rise}{run} =\frac{y1-y2}{x2-x1}

Find two coordinate points. Let's use (-2,4) and (0,-4). Based on this, we know that y1 is 4, y2 is -4, x1 is -2, and x2 is 0. Plug these into the formula:

\frac{4--4}{-2-0} =\frac{4+4}{-2} =\frac{8}{-2}=-4

Then, pick any point to plug into the equation. Let's use (0,-4)

Finally, plug everything into the equation:

y - - 4 = -4(x - 0)

y + 4 = -4x

y = -4x - 4

Gabrielle is 3 times older than mikhail. the sum of their ages is 80. how old is mikhail
skelet666 [1.2K]
The sum of their ages equals 80.
Gabrielle is 3 times older than Mikhail

Two numbers that have a sum of 80, with one number being 3 times the other are:
Gabrielle’s age: 60
Mikhail’s age: 20

60 + 20 = 80
20 x 3 = 60


Mikhail is 20 years old.
