A line contains the points (-7,15) and (10,27) what is the slope of the line as a simplified fraction?
Gwar [14]

Answer:

The slope of line for given points is   \frac{12}{17}

Step-by-step explanation:

Given points of line as :

A  = ( - 7 , 15 ) i, e x_1 = - 7 ,  x_1 = 15

B = ( 10 , 27 )  i.e  x_2 =  10 , y_2 = 27

Let The slope of line be m

So , The slope with two points is given as equation

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

Or, m =  \frac{27 - 15}{10 + 7}

Or, m =  \frac{12}{17}

Hence The slope of line for given points is   \frac{12}{17} .  Answer

What's the length of one leg of a right triangle if the length of the hypotenuse is 25 units and the length of the other leg is
OlgaM077 [116]

the length of the hypotenuse is 25 units and the length of the other leg is 15 units

To find the length of one leg of a right triangle we apply Pythagorean theorem

(one leg)^2 = hypotenuse ^2 - other leg ^2

Let x be the length of one log

hypotenuse = 25

other log = 15

x^2 = 25^2 - 15^2

x^2 = 625 - 225

x^2 = 400

Take square root on both sides

x = 20

The length of one leg = 20 units

Whats a function rule for this:<br> 7 less than three fifths of b is a
Elanso [62]
(3/5)b - 7 = a

Remember "of" means to multiply. Less than means subtraction: 7 less than means -7.
