Answer: C) 5
--------------
x = independent variable, y = dependent variable
Assuming this is a linear function, each increase of x by 2 leads to y going up by 10. So 10/2 = 5 is the unit increase each time x bumps up by 1.
-------------------
An alternative is to use the slope formula to get
m = (y2 - y1)/(x2 - x1)
m = (25 - 15)/(4 - 2)
m = 10/2 <--- this expression shows up again
m = 5 <---- leading to the same answer as before
So we see that the slope formula is a more drawn out method to finding the answer.

Answer:
270 flowers total she sell Together.
Step-by-step explanation:
According to the Question,
- Given, A florist arranges some orchids in bouquets of 20 and some roses in bouquets of 10.
Let, x = number of orchid bunches & y = number of rose bunches.
-
Now, She sells each orchid bouquet for $25 and each rose bouquet for $30. She earns a total of $390
Therefore, 25x + 30y = 390 ⇒⇒ Equation 1
she sells 4 times as many orchid bunches as rose bunches,
Therefore, x = 4y ⇒⇒ Equation 2
- Put The Value Of Equation 2 in Equation 1, We get
25 × (4y) + 30y = 390
100y + 30y = 390
130y = 390 ⇔ y = 390 / 130 ⇒ 3
if y = 3, then x = 4y must be equal to x= 12.
Thus, she sold 12 orchid bunches and 3 rose bunches.
- Verify, 25x + 30y = 390 ⇔ 12 × 25 + 3 × 30 = 390 (All okay)
Now, Each orchid bunch contains 20 flowers and each rose bunch contains 10 flowers.
- 12 × 20 + 3 × 10 = 240 + 30 ⇔ 270 flowers total she sell Together.
