Find the slope of the line that passes through (10,8) and (1,9).

lesya [120]

Answer:

$-\frac{1}{9}$

Step-by-step explanation:

between (1, 9) and (10, 8), the x moves by 9 and y moves by -1

The slope is equal to: $\frac{\Delta y}{\Delta x} = \frac{-1}{9} = -\frac{1}{9}$

3 & 4, And tell explanation<br><br> (P.S: Sorry for my sloppy handwriting)

3) Altitude / Time = y2 - y1 / x2 - x1 = 30 - 60 / 6 - 3
m = -30 / 3
m = -10

In short, constant rate of change is y = -10x

b) Constant proportionality exists between two quantities, as the amount of changing in Altitude over fixed period of time is same (constant) for every instance.

4) Sales / Day = y2-y1 / x2-x1 = 2,000 - 1,000 / 6 - 3
m = 1000 / 3
m = 333.3

a) In short, Constant relationship is y = 333.3x

b) Constant proportionality exists between two quantities, as the amount of changing in Sales over fixed days is same (constant) for every instance.

Hope this helps!

Answer:

Step-by-step explanation:

The Pythagorean triple (8, 15, 17) is often seen in algebra and geometry problems. You recognize it as choice A, so you know that is a right triangle.

A spreadsheet or graphing calculator can perform the tedium of comparing the sum of squares of the shorter sides to the square of the longer side. The attachment shows a spreadsheet used for that purpose. It identifies the triple (8, 15, 17) as the sides of a right triangle.
