What are we learning?
Daily Objective:
 Students will be able to construct a graph given the slope and a point on the line.
 Students will be able to construct a graph given the slope and y-intercept.
 Students will be able to illustrate and analyze real world problems involving the
definition of slope
TEKS/AP/Standards:
Ⓡ GEOM.7B Apply slopes and equations of lines to investigate geometric relationships,
including parallel lines, perpendicular lines, and special segments of triangles and other polygons.
Ⓡ GEOM.7C Derive and use formulas involving horizontal, vertical, and oblique distances, slope, and
midpoint and use in context to applications of distance and midpoint formulas.
How will we learn it?
Learning Activities:
Monday
Graphing Lines in Slope-Intercept Form
Graphing Lines Given a y-intercept and an ordered pair.
How will we tell if we’re learning it correctly?
Assessment Methods:
Teacher observation
Worksheets
Checks for Understanding:
Given a problem in Slope-intercept form, students will be able to graph the line using the
information provided.
Given a problem in which the y-intercept and an ordered pair are given, Students will be able
to graph a line.
What do I need to be successful?
An understanding of how to read a problem in slope-intercept form and determine what the
graph will look like.
Materials: Calculators, graphs, slope and y-intercept formula, worksheet
What do I need to do before next class?
Follow Up/HW:
Students will be given a study guide for the test that will be given Wednesday and Thursday.
Students will need to start studying for the test.
