Lesson Plan

Interpret the slope, the y-intercept, a coefficient, a term, the constant or a solution of a linear equation in two variables in its context, from the equation or from its graph, as a sentence with units

Interpret the slope of a contextual line as a rate of change, with units and direction, and the y-intercept as giving the output value when the input is zero, whether the line is given as an equation or as a graph with labeled axes

Interpret the coefficients, the terms and the constant of a constraint equation in standard form, where neither quantity is regarded as the input, and the intercepts and slope of its graph

Interpret a solution point of a two-variable equation in context

"For a linear equation in two variables that represents a context, interpret a solution, constant, variable, factor, or term based on the context, including situations where seeing structure provides an advantage." "Interpret the graph of a linear equation in the form Ax + By = C in a context." "A linear equation in two variables can be used to represent a constraint or condition on two variable quantities in situations where neither of the variables is regarded as an input or an output. A linear equation can also be used to represent a straight line in the coordinate plane."
