Answer:
The coordinates of the point is (3,5 , 400)
Step-by-step explanation:
The question is incomplete as the graph is not given in the question. Lets complete the question first. I have attached the graph related to this question below.
We can see in the graph that x-axis represents the years while the y-axis represents the pennies collected by Harry.
We have to find the coordinates of the point where he is able to collect 400 pennies.
As y-axis represents pennies, and the point to be found is at 400 pennies, so the y-coordinates of the point is 400.
Harry collects 400 pennies when he is halfway through 4rth year, which means that he has been collecting for:
3 years + Half of 4rth year = 3.5 years.
As x-axis represents the year and the point to be found is at 3.5 years, so the x-coordinate of the point is 3.5.
So, the coordinates of the point is (3,5 , 400)
This point can be seen in the second graph
Answer:
r = 4
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 5
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, r ) and (x₂, y₂ ) = (8, 9)
m = =
= 9 - r = 5 ( subtract 9 from both sides )
- r = - 4 ( multiply both sides by - 1 )
r = 4
