Answer:

y+2 = 2/3(x+2)

Step-by-step explanation:

We have 2 points (-2,-2) and (4,2)

so we can find the slope

m= (y2-y1)/(x2-x1)

= (2--2)/(4--2)

= (2+2) / (4+2)

= 4/6

= 2/3

The slope is 2/3

We can use point slope form to find the equation of the line

y-y1 = m(x-x1)

y--2 = m(x--2)

y+2 = 2/3(x+2)

Answer:y+2 = 2/3(x+2)

Step-by-step explanation:

You can’t find this answer by taking the two points on the line and setting them up as x-x and y-y and finding the slope And then using the slope to find the equation of the line.

Two sides of a triangle have the same length. The third side measures 3 m less than twice that length. The perimeter of the tria

Readme [11.4K]

Answer:

two sides have the length of 7m

third side is 11m

Step-by-step explanation:

perimeter is the sum of all sides

let 'n' = length of congruent sides

let '2n - 3' = length of third side

25 = n + n + 2n - 3

25 = 4n - 3

28 = 4n

n = 7m

2(7) - 3 = 11m

Which of the following expressions represents the GCF of 20 and 38?

AVprozaik [17]

Answer:

Option A

Step-by-step explanation:

For finding the greatest common factor of 20 and 38

We will have to make factors of both terms first,

So,

factors of 20:<u>2</u>*2*5

factors of 38=<u>2</u>*19

It can be seen that there is only one common factor between the factors of the two terms which is 2.

So the Greatest common factor of both the terms will be 2.

Hence, the correct answer is Option A ..

Write the equation of a line with a slope of –1 and a y-intercept of –6.

vazorg [7]

For this case the generic equation of the line is given by:

$y = mx + b$

Where,

m: slope of the line

b: intersection with the y axis

For this case we have:

$m = -1\\b = -6$

Therefore, substituting values in the generic equation we have:

$y = -x - 6$

Answer:

The equation of the line is:

$y = -x - 6$

option 1
