What is the slope of the line that contains these points?

Mathematics

Semmy [17]2 years ago

Answer:

-5

Step-by-step explanation:

Use the definition of slope:

m=\frac{y_2-y_1}{x_2-x_1}

And replace any two coordinates into the equation:

m=\frac{11-6}{13-14} \\m=\frac{5}{-1}\\m=-5

Answer:

m (slope) = -5

Step-by-step explanation:

All you need to do is use 2 of these points. For this example, we will use

(13,11) and (14,6).

To solve, use rise/run. The y value (rise) goes down by 5, so your rise is -5. The x value (run) goes up by 1, so your run is 1.

Insert these values into rise/run to get -5/1. Simplify this to get -5.

Answer:

see explanation

Step-by-step explanation:

Given the rule (x, y ) → (x + 5, - y )

Add 5 to the original x- coordinate and make the y- coordinate negative.

(a)

(5, 3 ) → (5 + 5, - 3 ) → (10, - 3 )

(b)

(- 2, 7 ) → (- 2 + 5, - 7 ) → (3, - 7 )

A class consists of 55% boys and 45% girls. It is observed that 25% of the class are boys and scored an A on the test, and 35% o
Julli [10]

Step-by-step explanation:

Probability of event A on the condition of event B is:

P(A|B) = P(A and B) / P(B)

P(scored an A | girl) = P(scored an A and girl) / P(girl)

P(scored an A | girl) = 0.35 / 0.45

P(scored an A | girl) = 0.778

The probability that a randomly selected girl also scored an A is 77.8%.

Which point could be on the line that is parallel to line KL and passes through point M?
professor190 [17]

Answer:

(8,-10)

Step-by-step explanation:

step 1

Find the slope of line KL

K(-6,8),L(6,0)

m=(0-8)/(6+6)

m=-8/12=-2/3

step 2

Find the slope of the line that is parallel to KL

we know that

If two lines are parallel , then their slopes are the same

therefore

The slope of the parallel line to KL is m=-2/3

step 3

Find the equation of the line parallel to KL that pass through the point M

M(-4,-2)

The equation of the line into point slope form is equal to

y-y1=m(x-x1)

substitute

y+2=-(2/3)(x+4)

step 4

Verify the points

we know that

If the point lie on the line, then the point must satisfy the equation of the line

case a) (-10,0)

substitute the value of x and the value of y in the equation and then compare the result

-10+2=-(2/3)(0+4)

-8=-8/3 -----> is not true

therefore

The point is not on the line

case b) (-6,2)

substitute the value of x and the value of y in the equation and then compare the result

2+2=-(2/3)(-6+4)

4=4/3 -----> is not true

therefore

The point is not on the line

case c) (0,-6)

substitute the value of x and the value of y in the equation and then compare the result

-6+2=-(2/3)(0+4)

-4=-8/3 -----> is not true

therefore

The point is not on the line

case d) (8,-10)

substitute the value of x and the value of y in the equation and then compare the result

-10+2=-(2/3)(8+4)

-8=-8 -----> is true

therefore

The point is on the line
