What is the slope of (10, 4), (4, 15)?

kakasveta [241]

Answer:

Slope is -11/6

Step-by-step explanation:

$Given \: points \: are \: (10,4) \: \: and \: (4,15) \\ slope \: = \frac{y2 - y1}{x2 - x1} \\ here \: x1 = 10 \: \: \: y1 = 4 \\ and \: \: x2 = 4 \: \: \: and \: \: y2 = 15 \\ on \: substituting \: the \: values \: in \: formula \\ slope = \frac{15 - 4}{4 - 10} \\ = \frac{11}{ - 6}$
