Aplumber charges a visitation fee of $60 and $45 per hour for time worked. if h is the number of hours worked and t is the total charge for completed work, then the variables are related by the equation
t = 45h + 60.
which variable is the independent variable?
a.
t
b.
h
c.
there is no relationship between the variables.

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
