Aim #27: How do we graph a line using the slope-intercept method?(Unit 3 - Graphing)

HW #27: Complete Classwork Practice

Do Now: 1) Which of the following pairs of points has the greatest rate of change?

a) (4, -3) and (6, 3) b) (-4, -2) and (-3, -7)

2) State the slope of each line.

a) y = 5 b) x = -8

Slope-intercept form of a Liney = mx + b

slope (m)(the coefficient of x)

y-intercept (b) (the constant)

Ex #1: y = 5x - 8

Ex #2: y = 7 - 4x

Ex #3: 2y = x

Proportional Relationship: The graph of a line that goes through the origin (0, 0). So, the y-intercept is always 0.

State the slope and y-intercept for each line.

Ex #4: y = 7

Ex #5: x = -3
