Could someone please explain to me how to solve this question?
Maksim231197 [3]

Answer:

y+2 = x+2

Step-by-step explanation:

A line is written in the point-slope form if its equation is in the form

y-y_1 = m(x-x_1)

where

m=\frac{y_2-y_1}{x_2-x_1} is the slope of the line, calculated using the two points (x_1,y_1) and (x_2,y_2)

In this problem, we have the following two points:

(x_1,y_1) = (-2,-2)\\(x_2,y_2)=(2,2)

Therefore we can calculate the slope of the line:

m=\frac{y_2-y_1}{x_2-x_1}=\frac{2-(-2)}{2-(-2)}=\frac{4}{4}=1

And so, the equation of the line in point-slope form is

y-(-2) = 1(x-(-2))\\\rightarrow y+2 = x+2

What is the y-coordinate of point D after a translation of (x, y) ? (x + 6, y – 4)?
Mandarinka [93]

Answer:

Y-coordinate = y - 4

Step-by-step explanation:

In the given question point D coordinate is (x, y)

and D after translation

x goes to 6 unit to the right and y goes to 4 unit down.

Hence,

          Y-coordinate = y-4

Example:From graph

              Let point D coordinate (x , y) = (2 , 3)

After rotation

              D coordinates is (x+6 , y-4) = (2+6 , 3_4) = (8 , -1)

3) Which property is used in the following: 4 x (5 + 7) = 4 x 5 + 4x7
earnstyle [38]

Answer:

3) D

4) B

5) A

6) 2 (x + 7)

Step-by-step explanation:

3)  

D. Distributive Property

The distributive property of multiplication over addition can be used when you multiply a number by a sum.

4)

B. 2 + 8 = 8 + 2

The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around.

5)

A. 4 x 1 = 4

The "Multiplicative Identity" is 1, because multiplying a number by 1 leaves it unchanged: a × 1 = 1 × a = a.

6)

3 ( x + 3) - X + 5

3x + 9 - x + 5

2x + 14

2 (x + 7)
