The graph of the linear equation y = 1/2x + 4 is attached
What is a linear function
A linear function consists of functions where the variables has exponents of 1.
The graph of linear functions is a straight line graph and the relationship is expressed in the form.
The linear equation in the slope intercept form: y = mx + c
definition of the variables:
y = output
m = slope
x = input
c = y intercept
Comparing with equation, y = -1/2 x + 4
m = -1/2
c = 4
