I know that the format for the equation is y = mx + b. Would b = 0 for the blue line and b = -4 for the red line?

The graph of f ( in blue ) is translated a whole number of units horizontally and vertically to obtain the graph of g ( in red )The function of is defined by f ( ) = xWrite down the expression for 8 ( x )8 ( 1 ) = 1
