1 answer:
The linear equation of the points is y = 2x + 3
<h3>How to determine the equation?</h3>The points are given as:
(-2, -1), (-1, 1), (0,3), (1,5), (2,7), (3,9)
From the above points, we can see that:
As x increases by 1, the y value increases by 2
This means that the points form a linear equation, and the slope (m) is calculated using:
m = Δy/Δx
This gives
m = 2/1
m = 1
The y-intercept (c) is when x = 0.
From the points, we have:
(x,y) = (0,3)
This means that
c = 3
A linear equation is represented as;
y = mx + c
Substitute the known values
y = 2x + 3
Hence, the linear equation of the points is y = 2x + 3

Answer:
24 inches represents 9 miles in the map
Step-by-step explanation:
To solve this problem you take into account that 8 inches represents 3 miles and that x represent the number of inches for 9 miles. That is:
8 ------- 3
x ------- 9
This is simply a rule of three, then you calculate:
Hence, 24 inches represents 9 miles in the map
