What is the slope of the line that passes through the points (–1, –17) and (–4, –2)?

Hello!

To find the slope of a line, we use the formula y2-y1/x2-x1.

Each ordered pair can either represent the 1,s or the 2,s and the slope will be the same. For our example, lets have (-1,-17) represent (x1,y1) and (-4.-2) represent (x2,y2). 

We will plug these values into the equation.

-2+17/-4+1
15/-3
-5

The slope of the line is -5, but let's check our answer by switching the 1's and 2's.

-17+2/-1+4
-15/3
-5

The slope of the line is -5.

I hope this helped you!

Solve for x: 1/8-2/×=5<br><br>someone pls help me ASAP
cricket20 [7]
Begin by subtracting 1/8 from both sides to get - \frac{2}{x} =5- \frac{1}{8} and get a common denominator of 8 on the right:- \frac{2}{x} = \frac{40}{8} - \frac{1}{8}.  Now simplify and cross-multiply: 39x = -16 andx = -16/39

Consider the accompanying data on flexural strength (MPa) for concrete beams of a certain type.
Vinvika [58]

Answer:

The point estimate for population mean is 8.129 Mpa.

Step-by-step explanation:

We are given the following in the question:

Data on flexural strength(MPa) for concrete beams of a certain type:

11.8, 7.7, 6.5, 6.8, 9.7, 6.8, 7.3, 7.9, 9.7, 8.7, 8.1, 8.5, 6.3, 7.0, 7.3, 7.4, 5.3, 9.0, 8.1, 11.3, 6.3, 7.2, 7.7, 7.8, 11.6, 10.7, 7.0

a) Point estimate of the mean value of strength for the conceptual population of all beams manufactured

We use the sample mean, \bar{x} as the point estimate for population mean.

Formula:

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

\bar{x} = \dfrac{\sum x_i}{n} = \dfrac{219.5}{27} = 8.129

Thus, the point estimate for population mean is 8.129 Mpa.
