I can’t help you with questions 1 because there is no picture. For question two, this is how you would find the slope given a line with 2 points:

Solving Steps: Reasoning:
1.) m=(y2-y1)/(x2-x1) [Slope Formula]
2.) m=(x1=-2, y1=-1) (x2=4, y2=3) [Assign Value to ordered pairs]
3.) m=(3-(-1))/(4-(-2)) [Substitution P.O.E.]
4.) m=(3+1)/(4+2) [Negative minus negative = positive]
5.) m=4/6 [Addition]
6.) m=2/3 [Simplification]

Therefore, the slope (m) = 2/3. To find the Domain, you will need to list all the X-coordinates from your ordered pairs. To find the range, you will need to list all the Y-coordinates from your ordered pairs.
You can use these formula:
Domain={x1, x2, x3, x4, x5…}
Range={y1, y2, y3, y4, y5…}
You just have to input your values into these formulas. An ordered pair looks like this: (5, 4). The left value is the x-coordinate (5), and the right value is the y-coordinate (4).

Margot is trying to decide between cable and satellite TV. Cable has a package of $49.99 a month for the basic package, plus $9.
VashaNatasha [74]
The cost of cable (c) in terms of months (m) is
  c = (49.99 +9.95 +9.95 -10.00)m
  c = 59.89m

The cost of satellite TV (s) in terms of months is
  s = 125.00 +49.95m

The difference in price is ...
  s - c = (125 +49.95m) -(59.89m)
  s - c = 125 -9.94m

At 12 months, the difference in price is
  s - c = 125 -9.94*12 = 5.72
This number is positive, which means ...
  the Cable company will save Margot money over a 12-month period.

At 24 months, the difference in price is
  s - c = 125 -9.94*24 = -113.56
This number is negative, which means ...
  the Satellite TV company will save Margot money over a 24-month period.


_____
A graph of the costs shows a cross-over at 12.5 months. Until then, the Cable provider is less expensive. Over terms longer than that, the Satellite TV provider is less expensive.

Give an example of this when adding two rationalnumbers with different signs and provide the product.
kolezko [41]

ANSWER:

\begin{gathered} \frac{4}{5}+-\frac{8}{3}=-\frac{28}{15} \\ \frac{4}{5}\cdot-\frac{8}{3}=-\frac{32}{15} \end{gathered}

STEP-BY-STEP EXPLANATION:

Rational numbers are all numbers that can be expressed as a fraction, that is, as the quotient of two whole numbers.

Therefore, an example would be:

\begin{gathered} \frac{4}{5}\text{ and - }\frac{8}{3} \\ \text{adding} \\ \frac{4}{5}+-\frac{8}{3}=\frac{4}{5}-\frac{8}{3} \\ \frac{4}{5}-\frac{8}{3}=\frac{4\cdot3-5\cdot8}{5\cdot3}=\frac{12-40}{15}=-\frac{28}{15} \\ \text{ product} \\ \frac{4}{5}\cdot-\frac{8}{3}=-\frac{4\cdot8}{5\cdot3}=-\frac{32}{15} \end{gathered}
