Answer:
y = 18.1x ; and y = 18x
Explanation:
The rate of change in Relationship B can be found by using the formula for slope:
Using the first two points, we have
We know that Relationship A has a lesser rate than this. The choices given for Relationship A are written in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept (in this case b = 0).
The slope of the first equation is 18.1; this is less than 18.25.
The slope of the second equation is 18.6; this is greater than 18.25.
The slope of the third equation is 18.3; this is greater than 18.25.
The slope of the fourth equation is 18; this is less than 18.25.
Let the consecutive odd integers be: x-5, x-3, x-1, x+1, x+3, x+5
Mean = 22
x = 22
Hence, the odd integers are 17, 19, 21, 23, 25.
The smallest integer is 17.
Mean = 22
x = 22
Hence, the odd integers are 17, 19, 21, 23, 25.
The smallest integer is 17.
