TX.8.5.C

Contrast bivariate sets of data that suggest a linear relationship with bivariate sets of data that do not suggest a linear relationship from a graphical representation

TX.8.5.E

Solve problems involving direct variation

TX.8.5.F

Distinguish between proportional and non-proportional situations using tables, graphs, and equations in the form y = kx or y = mx + b, where b ≠ 0

TX.8.5.G

Identify functions using sets of ordered pairs, tables, mappings, and graphs

TX.8.5.H

Identify examples of proportional and non-proportional functions that arise from mathematical and real-world problems

TX.8.5.I

Write an equation in the form y = mx + b to model a linear relationship between two quantities using verbal, numerical, tabular, and graphical representations

TX.8.6.A

Describe the volume formula V = Bh of a cylinder in terms of its base area and its height

TX.8.6.B

Model the relationship between the volume of a cylinder and a cone having both congruent bases and heights and connect that relationship to the formulas

TX.8.6.C

Use models and diagrams to explain the Pythagorean theorem

TX.8.7.A

Solve problems involving the volume of cylinders, cones, and spheres

TX.8.7.B

Use previous knowledge of surface area to make connections to the formulas for lateral and total surface area and determine solutions for problems involving rectangular prisms, triangular prisms, and cylinders

TX.8.7.C

Use the Pythagorean Theorem and its converse to solve problems

TX.8.7.D

Determine the distance between two points on a coordinate plane using the Pythagorean Theorem

TX.8.8.A

Write one-variable equations or inequalities with variables on both sides that represent problems using rational number coefficients and constants

TX.8.8.B

Write a corresponding real-world problem when given a one-variable equation or inequality with variables on both sides of the equal sign using rational number coefficients and constants

TX.8.8.C

Model and solve one-variable equations with variables on both sides of the equal sign that represent mathematical and real-world problems using rational number coefficients and constants

TX.8.8.D

Use informal arguments to establish facts about the angle sum and exterior angle of triangles, the angles created when parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles

TX.8.9

Identify and verify the values of x and y that simultaneously satisfy two linear equations in the form y = mx + b from the intersections of the graphed equations

TX.8.10.A

Generalize the properties of orientation and congruence of rotations, reflections, translations, and dilations of two-dimensional shapes on a coordinate plane

TX.8.10.B

Differentiate between transformations that preserve congruence and those that do not

TX.8.11.A

Construct a scatterplot and describe the observed data to address questions of association such as linear, non-linear, and no association between bivariate data

TX.8.11.B

Determine the mean absolute deviation and use this quantity as a measure of the average distance data are from the mean using a data set of no more than 10 data points

TX.8.11.C

Simulate generating random samples of the same size from a population with known characteristics to develop the notion of a random sample being representative of the population from which it was selected

TX.8.12.A

Solve real-world problems comparing how interest rate and loan length affect the cost of credit

TX.8.12.B

Calculate the total cost of repaying a loan, including credit cards and easy access loans, under various rates of interest and over different periods using an online calculator
