Algebra 1 Remediation September 6 Page 392
Perpendicular Lines • Slopes are opposite reciprocals
Parallel Lines • Same slope with different y-intercepts.
Page 392 #1, 2, 4 • Ax + By = C • Slope = - A / B
Page 392 #4 • Graph the lines in the calculator • Identify the point of intersection
Number of solutions • How many solutions does the following system have? • y = 4x + 1 • y = x2 + 4 • Graph in calculator and count intersections.
Scatter Plots • Non-linear relationship
