Which function is represented by the graph?
A)f(x) = 2x + 6B)f(x) = 1/2x + 6C)f(x) = -2x + 6D)f(x) = -1/2x + 6
The line falls from left to right.....so we have a negative slope.....this eliminates answers A and B
The y intercept = (0, 6)
The x intercept is ( 12 0)
Slope = ( 6 - 0 ) / ( 0 - 12) = 6 / - 12 = - 1/ 2
D is correct
