Unit 3, Lesson 10

Calculemos la pendiente

Grado 8

Practice

Problem 1

Para cada gráfica, calcula la pendiente de la recta.

Graph of a line labelled A.<br> — A

Graph of a line labelled B. — B

Graph of a line labelled C. — C

Problem 2

Asocia cada par de puntos con la pendiente de la recta que pasa por ellos.

\((9,10)\) y \((7,2)\)
\((\text-8,\text-11)\) y \((\text-1,\text-5)\)
\((5,\text-6)\) y \((2,3)\)
\((6,3)\) y \((5,\text-1)\)
\((4,7)\) y \((6,2)\)

4
\(\text-3\)
\(\text-\frac52\)
\(\frac67\)

Problem 3

Selecciona todos los puntos que podrían estar en una recta que pasa por el punto \((10,1)\) si la recta tiene pendiente negativa.

\((2,6)\)
\((\text-1,0)\)
\((\text-4,7)\)
\((11,0)\)
\((2,\text-2)\)
