What is the actual slope of this line?

Mathematics
1 answer:
-BARSIC- [3]2 years ago
5 0

Answer:

  -4

Step-by-step explanation:

The line has a "rise" between the two points of -4 units for a "run" of +1 unit. The slope is the ratio ...

  m = rise/run = -4/1 = -4.

The slope is -4.

_____

<em>Additional comment</em>

A "whole number" must be non-negative. Here, the slope is negative. If you're restricted to "a fraction or a whole number", then the appropriate answer is the fraction -4/1. We suspect that "integer" is meant where "whole number" is used.

Hallie bikes 1 5/8 km before lunch 6 1/4 km How much farther does hallies bike after lunch than before lunch? Express your answe
kondaur [170]

Distance biked before lunch = 1\frac{5}{8} km (the number is written in mixed fraction)

⇒ Distance biked before lunch = \frac{13}{8}

Distance biked after lunch = 6\frac{1}{4} km (the number is written in mixed fraction)

⇒ Distance biked after lunch = \frac{25}{4}

We need to determine how much farther does Hallie bike after lunch than before lunch

Extra distance biked after lunch vs. before lunch = \frac{25}{4} - \frac{13}{8}

⇒ Extra distance biked after lunch vs. before lunch = \frac{50-13}{8}

⇒ Extra distance biked after lunch vs. before lunch = \frac{37}{8}

⇒ Extra distance biked after lunch vs. before lunch = 4\frac{5}{8} (in mixed fraction)

Hence, Hallie biked 4\frac{5}{8} km extra after lunch vs. before lunch.

What is the answer to this equation using substitution x+y=1
FromTheMoon [43]
{   x + y = 1    * ( - 2 )
  2 x + 3y = -4

- 2 x - 2 y = - 2
  2 x + 3 y = - 4
_______________
         y = - 6

Subsititute y = - 6 
<span>
2 x + 3 y = - 4

2 x + 3 * (-6) = -4

2 x - 18 = - 4

2 x = - 4 + 18

2 x = 14

x = 14 / 2

x = 7

The solution  to the system of equations are:

x = 7 and y = - 6
