5.4 The Slope - Intercept Form pg. 244 to 251
Recall --How do you find an equation from a table of
values? (ch. 1)
1. Find the constant difference
2. Find the intial value at 0.
3. Substitute info into equation
The constant difference indicates a Linear Pattern!
Rate is constant!!!!!
Rate IS the slope!
The value when x = 0 is called the y - intercept.
-the ordered pair where the line crosses the y axis
always (0, # on y axis)
In a linear equation (equation for a line):
y = mx + b
y and x REMAIN as the variables because they change
depending on the number used for x
m represents the slope
b represents the y-intercept
