The linear function given by the equation y = 3x has a slope of 3.
Linear equation
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and y is the initial value of y.
Given the linear function:
y = 3x
when x = 1; y = 3(1) = 3
when x = 2; y = 3(2) = 6
when x = 3; y = 3(3) = 9
The linear function given by the equation y = 3x has a slope of 3.
