The domain of f(x) = 24x + 7 is all real numbers except where the expression is undefined. in this case, there is no real number that makes the expression undefined.
hope this helps, God bless!
The rate of change of a linear equation (first degree) is equivalent to the slope of a line. Slope is described as the vertical movement (rise) of the line over its horizontal counterpart (run). In determining the rate of change or slope (m) given 1 data point (x',y'), point-slope form is applicable. Point-slope form is: (y-y') = m (x-x'). Substitute the given point (-5,-1) in the equation. By substitution, [y-(-1)] = m [x-(-5)]. Re-arranging the equation, the rate of change or slope is, m = (y+1)/(x+5).

Answer:
y=x+31.25
Because x stand for cauclator so 31.25 per x so it would end up being x+31.25
