Question

this graph shows how the number of flowers ron can have in his garden is related to the number of seed packets he purchases. flowers in rons garden how many seed packets does ron need to have a total of 40 flowers in his garden? \\(\square\\) seed packets

Explanation:

Step1: Identify line equation form

The graph is linear, use $y=mx+b$.

Step2: Find y-intercept $b$

When $x=0$, $y=4$, so $b=4$.

Step3: Calculate slope $m$

Use point $(10,45)$: $m=\frac{45-4}{10-0}=\frac{41}{10}=4.1$, but use graph lookup: find $y=40$ on y-axis, move horizontally to the line, then down to x-axis.

Step4: Locate 40 flowers on graph

From $y=40$, trace to line, then to x-axis: $x=9$.

Answer:

9 seed packets
