Answer:

(Going clockwise from top left.) Rotation, Reflection across the x-axis, Reflection across the y-axis, translation.

Step-by-step explanation:

In picture one, the triangle seems to be rotated.

In picture two, the triangle is reflected across the x-axis.

Picture 3 has the triangle reflected as well, but this time it is across the y-axis.

Picture 4 has the triangle translated. It has no change in mirroring but it has a change in position.

Help please. <br> Give the slope of y - 3 = 4(x + 8) and a point on the line

Sauron [17]

-----------------------------------------------------------
Make y the subject :
-----------------------------------------------------------
y - 3 = 4(x + 8)
y - 3 = 4x + 32 // Apply distributive property
y = 4x + 35 // Add 3 to both sides

-----------------------------------------------------------
Identify Slope :
-----------------------------------------------------------
Slope = 4

-----------------------------------------------------------
Find a point on the line :
-----------------------------------------------------------
When x = 0,
y = 4(0) + 35 // Sub x = 0 into the equation
y = 35 // Combine like terms
Point = (0, 35)

-----------------------------------------------------------
Answers :
(a) Slope = 4
(b) One point on the line is (0, 35)

Solve by elimination <br> 3x+2y=19<br> -9x+8y=-29

Alja [10]

Step-by-step explanation:

(3x + 2y =19)(3)

-9x + 8y =-29

9x + 6y = 57 <em><u>NOTE</u></em><em><u>:</u></em> we cross here 9x in first

-9x + 8y = -29 we cross here - 9x in second

Since 9x and - 9x are opposite

___________

6y +8y = 57 - 29
