Acable installer charges $40.00 per hour plus a $60.00 service charge. your father's firm hires him to hookup his company's internet service. find the total charges it takes the cable installer 8.5 hours to complete the task.

40x8.5=340+60=$400 for 8 hours and 30 minutes of service

40 times 8. then add 60.

y+4=-4(x-2)


slope-intercept form takes the form of: y=mx+b
where m is the slope and b is the value at which the line intercept the y-axis


then we can write- after simplification:
y+4=-4(x-2)
y+4=-4x+8
y=4x+8-4
y=4x+4

m=4 and b=4

that is the slope intercept form

hope that helps
