Answer:

-4

Step-by-step explanation:

The point (x, y) = (0, 0) is on the line, so it represents a <em>proportional relation</em>. Any ratio of y to x will be the slope. The choice that makes this computation easiest is ...

x = 1, y = -4

y/x = -4/1 = -4

The slope of the line is -4.

-2 2/3 divided by 4/3

Vedmedyk [2.9K]

Answer:

-2

Step-by-step explanation:

$Rule(s): a\frac{b}{c} = \frac{a \cdot c + b}{c}, \frac{-a}{b}=-\frac{a}{b}, \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c} \\2\frac{2}{3}=\frac{2\cdot 3+2}{3}\\=\frac{8}{3}\\=\frac{-\frac{8}{3}}{\frac{4}{3}}\\=-\frac{\frac{8}{3}}{\frac{4}{3}}\\=\frac{-8\cdot \:3}{3\cdot \:4}\\= \frac{-24}{12}\\= -2$
