Calculate, using technology, the correlation coefficient between two quantitative variables and interpret this quantity as a measure of the strength of the linear association
TEKS
Communicate mathematical ideas, reasoning, and their implications using multiple representations, including symbols, diagrams, graphs, and language as appropriate
TEKS
Decide whether relations represented verbally, tabularly, graphically, and symbolically define a function

TEKS
Determine the effects on the graph of the parent function f(x) = x2 when f(x) is replaced by af(x), f(x) + d, f(x - c), f(bx) for specific values of a, b, c, and d
TEKS
Determine the slope of a line given a table of values, a graph, two points on the line, and an equation written in various forms, including y = mx + b, Ax + By = C, and y - y1 =
TEKS
Display, explain, and justify mathematical ideas and arguments using precise mathematical language in written or oral communication
TEKS
Estimate graphically the solutions to systems of two linear equations with two variables in real-world problems
TEKS
Factor, if possible, trinomials with real factors in the form ax2 + bx + c, including perfect square trinomials of degree two
TEKS
Graph quadratic functions on the coordinate plane and use the graph to identify key attributes, if possible, including x-intercept, y-intercept, zeros, maximum value, minimum
TEKS
Identify terms of arithmetic and geometric sequences when the sequences are given in function form using recursive processes
TEKS
Number and algebraic methods. The student applies the mathematical process standards and algebraic methods to rewrite algebraic expressions into equivalent forms
TEKS
Quadratic functions and equations. The student applies the mathematical process standards to solve, with and without technology, quadratic equations and evaluate the reasonableness of their solutions. The student formulates statistical relationships and evaluates their reasonableness based on real-world data
