6. Ceramics A friend is helping you cut mosaic tiles. Your friend brings you four tiles. The tiles need to have the same slope as the equation y equals , 2 fifths , x . Select each tile you can use.
7. Multiple Representations
a. Identify the slope triangle that can be used to find the slope of the line with the equation y equals , 1 half , x plus 7 .
b. Draw two other triangles that can be used to find the slope of the line.
8. Think About the Process
a. What is the first step to find the ratio of the rise to the run of the given triangle?
b. What is the ratio of the rise to the run of the given triangle?
c. Draw a graph that shows the triangle that is the image of the given triangle after a dilation with center (0, 0) and a scale factor of 1 fourth .
d. What do you know about the ratio of the rise to the run of the image triangle?
9. Think About the Process The slope of the given line is 1 third . One slope triangle is shown. Another slope triangle with a ratio of the rise to the run of 1 third has vertices at (9, 2) and (12, 2).
a. What do you know about the second triangle?
b. Find the coordinates of the third vertex.
