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 Line
y = mx + b
slope (m)
y-intercept (b)
(the coefficient of x)
(the constant)
State the slope and y-intercept for each line.
Ex #1:
y = 5x - 8
Ex #2:
y = 7 - 4x
Ex #3:
2y = x
Ex #4:
y=7
Ex #5:
x = -3
Proportional Relationship : The graph of a line that goes
through the origin (0, 0). So, the y-intercept is always 0.
