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

4. Muthu had 4 times as many stamps as
RSB [31]

Answer:

20 stamps

Step-by-step explanation:

Let x be Muthu's original count

Let y be Sangeetha's original count

x = 4y

x - 12 = y + 12

y = x - 24

x = 4(x - 24)

x = 4x - 96

3x = 96

x = 32

so 32 - 12 = 20

What are the missing angle measures in triangle ABC?
Finger [1]

we know that

In the right triangle ABC

∠A+∠B=90 ------> by complementary angles

so

Step 1

Find the measure of angle B

we know that

tan\  B=\frac{opposite\  side\  angle\  B}{adjacent\  side\  angle\  B}

in this problem

opposite\  side\  angle\  B=7in\\ adjacent\  side\  angle\  B=5in

so

tan\  B=\frac{7}{5} \\ \\ B=arc\ tan\frac{7}{5} \\ \\ B=54.5\ degrees

Step 2

Find the measure of angle A

A+B=90\\ A=90-B\\ A=90-54.5\\ A=35.5\ degrees

therefore

the answer is the option

35.5° and 54.5°

What is the length of a diagonal of a rectangle 9m long and 5m wide?
Zarrin [17]
Pythagorean Theorem: a^2 + b^2 = c^2

(5)^2 + (9)^2 = c^2
25 + 81 = c^2
106 = c^2
c = square root of 106

Length of a diagonal of a rectangle is square root of 106.
