f(x) is the value of the function. m is the slope of the line. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane. x is the value of the x-coordinate. I'm done hopefully it help
The answer would be the algebraic expression, b + 9. The
translation here is b is representing the number of blue bikes then you needed
to add the 9 which represents the 9 red bikes. The two is added together, to get
the total of those red and blue bikes which we are looking for.
