Acomputer technician charges a flat rate for home visits plus $55 per hour. the technician bills $190 for a 2-hour home visit to install a new hard drive. the equation y − 190 = 55(x − 2) gives the total amount y the technician charges for x hours of work. what is the equation in slope-intercept form

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.

The answer should be c.
