The table representing a linear function that has a lower rate of change than this function y = 2x − 5 is: Table A
What is the rate of change of the function?
The rate of change of a function is also known as slope of the function.
The general formula for linear equation in slope intercept form is:
y = mx + c
where:
m is slope
c is y-intercept
Thus:
Rate of change of the line y = 2x - 5 is:
m = 2
Rate of change of table A is:
m = (-2 - 3)/(1 - 0)
m = -5
Rate of change of table B is:
m = (7 - 3)/(1 - 0)
m = 4
Rate of change of table C is:
m = (-2 - (-4))/(1 - 0)
m = 2
We see that the least rate of change is -5 which is given by table A and is lesser than that of the given equation which has a rate of change of 2.
