determine if the relation y = 4x - 1 is a function
(1)
determine if 7x2 + y = 5 is a linear or non linear function (the functions 7x2 + y = 5 is a nonlinear function)
determine if the given graph is the graph of the function y = -2/5x + 3 (1)

write the equation of the linear function (y = 3x - 2)
last year slays ordered 4 cubic yards of soil and spent $220. this year (y= 40x + 60)
compare linear function 1 with linear function 2 (linear function 2 has the greater rate of change)
The given information is not sufficient to determine if y = 4x - 1 is a function (1).
The equation 7x^2 + y = 5 is a nonlinear function.
Without the graph provided, we cannot determine if it is the graph of y = -2/5x + 3 (1).
The initial value is 10 and the rate of change is 1.7.
The initial value is 21 and the rate of change is 0.5.
The initial value is 3 and the rate of change is -1/3.
The rate of change is 5 feet per minute.
Without additional information, we cannot determine the initial weight of the pan with four eggs (12oz).
The initial value is $300.
The equation y = mx + 6 defines a linear function.
The equation of the linear function is y = 3x - 2.
Without additional information, we cannot compare linear function 1 with linear function 2.
