# What is the slope of a line that passes through the point (-2,-5) and (18,-5)?

###### Question:

## Answers

0/1

step by step explanation:

0

Step-by-step explanation:

m = y₂ - y₁/x₂ - x₁

m = -5 - (-5)/18 - (-2)

m = 0/20

The slope is 0 meaning no steepness

The line is vertical

1. (-2,5)(1,4)

slope = (4 - 5) / (1 - (-2) = -1 / 3

2. (11,13)(8,18)

3. (6,y)(10,-1)

slope = (-1 - y) / (10 - 6) = (-1- (-2) / 4 = 1/4

y = -2

4. undefined

5. (2,110)(3,165)

slope = (165 - 110) / (3 - 2) = 55/1

this basically means that to rent a charter boat, it will cost 55 per person

1. The answer would be 1/4To find the slope, you use this formula:slope: y1-y2/x1-x2You need to determine two points. In this case, let use the point where y=0 and y=1 which was x1, y1= (-4,0) and x2, y2= (0,1)

The calculation would be:slope: y1-y2/x1-x2slope: (1-0)/ (0- -4)= 1/4

2. The answer would be: -3

There is 2 different coordinate in this question which was:

x1,y1= (-5.2, 8.7)

x2,y2=(-3.2, 2.7)

Using the same slope formula, you can get this equation

slope: y1-y2/x1-x2slope: 8.7-2.7/(-5.2) - (-3.2)slope: 6/-2slope= -3

3. The answer is: C. Y-18=9(x-2)

Let say that the plant height is in Y-axis and the month in X-axis. Then you can get 4 coordinate, but we just need two. The list of coordinate would be:

x1,y1= (2, 18)

x2,y2=(4, 36)

Using the slope formula you can get the m variable for point-slope form

slope: y1-y2/x1-x2slope: 18-36/2-4slope: -18/-2= 9

Since the slope is 9 (m=9), the point-slope form would be:

y-y1=m(x-x1)

y-18= 9(x-2)

A: -25/2

Step-by-step explanation:

(2×3)=6

(4×5)=20.

6×20=120

-2/25

Step-by-step explanation:

use the formula y2-y1/x2-x1

14-18/30-(-20)

-4/50

-2/25

1) The correct option is C. (2) The correct option is D. (3) The correct option is B. (4) The correct option is D. (5) The correct option is D.

Step-by-step explanation:

The slope formula is

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

(1)

Two points are (-2,5) and (1,4).

[tex]m=\frac{4-5}{1-(-2)}=\frac{-1}{3}tex]</p<pTherefore option C is correct.</p<p(2)</p<pUse the above mentioned formula for each pair of coordinates.</p<p[tex]m=\frac{10-13}{17-12}=\frac{-3}{5}[/tex]

[tex]m=\frac{10-15}{13-16}=\frac{-5}{-3}=\frac{5}{3}[/tex]

[tex]m=\frac{10-7}{3-0}=\frac{3}{3}=1[/tex]

[tex]m=\frac{18-13}{8-11}=\frac{5}{-3}=\frac{-5}{3}[/tex]

Therefore option D is correct.

(3)

The pair of points (6, y) and (10, -1). The slope is [tex]\frac{1}{4}[/tex].

[tex]\frac{1}{4}=\frac{-1-y}{10-6}[/tex]

[tex]\frac{1}{4}=\frac{-1-y}{4}[/tex]

[tex]1=-1-y[/tex]

[tex]y=-2[/tex]

Therefore option B is correct.

(4)

For vertical line the x coordinates always remains the same. Therefore when we subtract the same number we get zero in the denominator, therefore the value of slope is undefined for a vertical line.

Therefore option D is correct.

(5)

Two points from the table are (2,110) and (3,165).

[tex]m=\frac{165-110}{3-2}=\frac{55}{1}[/tex]

Therefore option D is correct.

1. 5/2 2. -1/4 3. 0 4. 2 and 5. -1

2/5

Step-by-step explanation:

Slope of line is also called the gradient of line.

The formula of gradient of a straight line is always (y1-y2)/(x1-x2)
