Product details & bulk quoteTEKS Math 8.4(A)Supplemental connection
Use similar right triangles to show the slope ratio is constant for any two points on a line.
Pair the formula board with similar-right-triangle instruction; substitution alone does not establish this geometric relationship.
TEKS Math 8.4(C)Direct connection
Determine rate of change or slope and y-intercept using table or graph data.
Calculate the slope component using points from tables or graphs. Y-intercept and contextual interpretation require accompanying instruction.
Helps students calculate slope using rise over run and interpret slope as a rate of change. Supports mathematics instruction involving linear relationships and science instruction involving speed calculations from distance-time graphs.
