Explanation:
The slope intercept form of a linear equation is given by :-
, where m is the slope of the line and c is the initial value.
Given : A moving firm charges a flat fee of $35 plus $30 per hour.
i.e.Slope (rater of change) =$30 per hour
Initial value = $35
Let 'y' be the cost in dollars of using the moving firm for 'x' hours,then we the following slope-intercept form of the equation :-
