Pick two points. For example, (0,3) and (2,4)
First, find the slope:
![\text{Slope } = \frac{ y_2 - y_1 } { x_2 - x_1 } = \frac{ 4 - 3}{ 2 - 0}=\boxed{\bf{ \frac{ 1}{ 2}}}](https://tex.z-dn.net/?f=%5Ctext%7BSlope%20%7D%20%3D%20%5Cfrac%7B%20y_2%20-%20y_1%20%7D%20%7B%20x_2%20-%20x_1%20%7D%20%3D%20%20%20%20%5Cfrac%7B%204%20-%20%203%7D%7B%202%20-%200%7D%3D%5Cboxed%7B%5Cbf%7B%20%20%5Cfrac%7B%201%7D%7B%202%7D%7D%7D)
The slope is 1/2.
Now we have this much of the equation:
y = 1/2x + b
Plug in the point (0,3) to find the value of b
3 = (1/2)(0) + b
b = 3
Your final equation is
y = 1/2x + 3.

Answer: x ≥ 40
Step-by-step explanation:
Hi, to answer this question and write the inequality we have to analyze the information given:
Each afternoon at least 40 people buy coffee in a coffee shop
In Math, at least means more or equal (≥).
So, if X represents the number of people who buy coffee in an afternoon, the inequality is (Mathematically speaking)
:
X ≥ 40
