Find the slope and the y-intercept of the graph of the linear equation. 1. y=3x-7 2. y-1=-2/3x

Answers

Answer 1

Answer:

1) Slope: 3; y-intercept: -7

2) Slope: 2/3; y-intercept: 1

Step-by-step explanation:

y = mx + b; m is slope and b is y-intercept

1. y = 3x - 7

The equation is already in slope-intercept form, so you can find the slope and intercept.

Slope: 3

y-intercept: -7

2. y - 1 = 2/3x

For this one, you have to convert this into slope-intercept form (solving for y)

y - 1 = 2/3x

Add 1 to both sides

y - 1 + 1 = 2/3x + 1

y = 2/3x + 1

Now that the equation is in slope-intercept form, you can get the slope and y-intercept.

Slope: 2/3

y-intercept: 1

What is the image of (8,-6) after a reflection over the line y = x?

Answers

Answer:

Step-by-step explanation:

Interchange x and y: (-6, 8) is the image of (8, -6) after a reflection over y = x.

The image of (8,-6) after a reflection over the line y=x is (-6, 8).

The given coordinate point is (8, -6).

What is a reflection over the line y=x?

Reflect over the y = x, when you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed).

The image of (8,-6) after a reflection over the line y=x is

Reflecting in the line y = x interchanges the x and y coordinates. So, the image of (8, -6) is (-6, 8).

Therefore, the image of (8,-6) after a reflection over the line y=x is (-6, 8).

C. An elephant walks with a speed of 15 steps a minute. How long was the elephant walking if she walked without stopping for 480 steps?

Step-by-step explanation:

Sry when Its wrong

Answer:

sin• = √13/7

tan•= -√13/4

Step-by-step explanation:

sin2•+ cos2• = 1

sin• = √1-cos2•

sin•= √1-(-4/7)2

sin•= √1-16/49

sin•= √ 49-16/49

sin•= √ 13/ 49

sin•= √13/7

tan• = sin•\cos•
