Answer:
use Desmos where you could see the graph. And they intersect in (4,3)
Step-by-step explanation:
hopefully that works
I think the greatest possible starting number would be 1,214,449. If it was any higher, like 1,214,450, then the number would round up to 1,214,500, and you don't want that.
Hopefully this helps! Let me know if you have any more questions.
Answer:
y = (2/3)x + 1/3
Step-by-step explanation:
Check that a single straight line will actually go through all four of these points. Going from (1, 1) to (4, 3), the 'rise' is 2 and the 'run' is 3, which would make the slope, m, equal rise/run = 2/3. Going from (4,3) to (10, 7), m = rise/run = 4/6 = 2/3 (again).
Let's find the slope-intercept form of the equation of this line: y = mx + b
Arbitrarily choose the point (1, 1). Here x = 1, y = 1 and m = 2/3. Then
we have
1 = (2/3)(1) + b, or 1 = 2/3 + b, so that b must be 1/3.
The equation in question is y = (2/3)x + 1/3
It’s 3! it’s not the confusing once you understand it so i’ll try and help. The constant rate of proportionality is basically it’s constant rate of change. So you look at the graph and see what y equals when x is one. If you can’t than keep going until you see for example that 2 x is at 6 y than you would divide 6 by 2 and get 3. Hope that helps!
