Answer:

Step-by-step explanation:

Let the unknown number be x

Five times the number is expressed as 5x

28 greater than the product of the number and -2 is expressed as;

28 + (-2x)

Equating both expressions

5x = 28 + (-2x)

5x = 28 - 2x

5x+2x = 28

7x = 28

x = 28/7

x = 4

Hence the number is 4

FrozenT [24]

Use the slope equation: $\frac{y2-y1}{x2-x1}$

Plug in the points (2, 15) and (0, -1).
$\frac{-1-15}{0-2}$ ⇒ $\frac{-16}{-2}$ = 8

The slope of the line is 8.
