WILL GIVE MEDAL FOR ANSWER THATS ACTUALLY HELPFULL



A machine produces parts at a constant rate as shown in the table. What is the constant rate of change of parts produced per hour?
# of Parts 1450 3625
Time (h) 2 5




a 625 parts per hour

b 675 parts per hour

c 725 parts per hour

d 745 parts per hour

Answer 1

Let time be the x coordinate and the other number be y
Such that (time, # of parts)

So you have (2,1450) and (5, 3625)

When it's asking for constant rate of change , it's the same as asking the slope of the line that passes through these 2 points

Answer 2

Remember

y2-y1
------- = slope
x2-x1

Answer 3

Plug them in

3625-1450
------------- = ?
5. - 3
