The inequality shows that she can only invite less than 50 people, and you can not invite a fraction or decimal , so the maximum is 49.
You miles in a car is 32miles
It should end in between 8 and 10 so it'd be considered 9
The equation representing the real-world scenario is linear as shown io the graph.
Generally, a linear equation takes the form:

The slope (m) is calculated using the formula:

On the line, we have the points: (0, 1600), (4, 1200)
Substituting we have:

The y-intercept is the value of the y-axis when the line cuts the y-axis
y-intercept : (0, 1600)
Hence, the equation is:
