Unit 3, Lesson 10

Calculating Slope

Grade 8

Practice

Problem 1

For each graph, calculate the slope of the line.

Graph of a line labelled A.<br> — A

Graph of a line labelled B. — B

Graph of a line labelled C. — C

Problem 2

Match each pair of points with the slope of the line that passes through each pair.

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

4
\(\text-3\)
\(\text-\dfrac52\)
\(\dfrac67\)

Problem 3

Select all of the points that could be on a line with the point \((10,1)\) if the line has a negative slope.

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