Given algebraic, tabular, or graphical representations of linear functions, the student will determine the intercepts of the graphs and the zeros of the function.
Concord Consortium
Concord Consortium: Linear Equations: Y=mx+b
Graph lines using a slope and a y-intercept. Identify the slope and y-intercept from the equation of a line in slope-intercept form.
Math Open Reference
Math Open Reference: Equations of a Line (Slope and Intercept Form)
The interactive resource investigates slope and intercept. Students adjust the sliders to control the slope (m) and the intercept (b) of the line. The equation and the line will change accordingly. Learners can also drag the origin.
