<h3>Answer: m = 2, b = 1</h3>

The y intercept is where the graph crosses the vertical y axis. In this case, it's at the point (0,-1). Focus on the y coordinate and we see y = -1. The y intercept is b = -1.

The slope is m = 2 because we start at a point like the y intercept, and do the following steps

go up 2
go over to the right 1

and arrive at the point (1,1) which is also on the graph. We can follow these steps again to go from (1,1) to (2,3) and so on.

Alternatively, you can pick two points on the graph such as (1,1) and (2,3) to use the slope formula

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

m = (3-1)/(2-1)

m = 2/1

m = 2

Either way, the slope is 2.

10(-3n + 8) = 380 pls find n

Flauer [41]

Answer:

n = - 10

Step-by-step explanation:

10(-3n + 8) = 380

-30n + 80 = 380

80 - 380 = 30n

30n = - 300

n = - 300 : 30

n = - 10

which of the following best describe the blue line in the image below A. The line constructed through point P that is parallel t

lesya692 [45]

Answer:

Option B.

Step-by-step explanation:

Option A. "The line constructed through point P that is parallel to line B."

Since parallel lines never intersect each other, a line intersecting line AB at point P will not be parallel.

Therefore, Option (A) is incorrect.

Option (B). "The line constructed through point P that is perpendicular to line AB."

Since the angle between line AB and a line constructed through point P has been given as 90°, line through point P will be perpendicular to AB.

Therefore, Option (B) is the answer.

Option C. "The line constructed through point P that intersects line AB at two different points."

Since, two perpendicular lines intersect each other at only one point, the line constructed from point P will not intersect line AB at two different points.

Therefore, Option C is not correct.

What is the additive inverse of the complex number 9 Ă˘â‚¬"" 4i? Ă˘â‚¬""9 Ă˘â‚¬"" 4i Ă˘â‚¬""9 4i 9 Ă˘â‚¬"" 4i 9 4i.

hram777 [196]

Additive inverse is the number you add to a given number to make the sum zero. The addition of both the number must be zero to make both numbers additive inverse.. The additive inverse of the given complex number is

$-9+4i$

<h3>Addictive Inverse</h3>

Addictive Inverse-Additive inverse is the number you add to a given number to make the sum zero. The addition of both the number must be zero to make both numbers additive inverse.

Let an example, if we take the number 10 and add -10 to it. Thus -10 is the additive inverse of the number 10.

Here, the given number is a complex number. A complex number is a number of the form a + bi, where a and b are real numbers. The given function is,

$9-4i$
