Comparing Functions 1
Which has a greater rate of change?
x y OR y= 6x + 3
3 5
4 9
y=6x + 3 because the table has a slope of 4 when you use the formula
Does this table represent a function?
x y
4 8
4 9
4 10
No, x values are repeated
What is the equation in slope intercept form when given 3/4 as the slope and (0,-2) as an ordered pair?
3/4x - 2
Determine the rate of change?
(5,12) (3, 9)
3/2
Which has a greater y-intercept?
x y OR y=2x - 1
-1 5
0 4
1 2
The table, because where x is 0, y is the intercpet which is 4.
