Answer:
y = x - 7
Explanation:
The equation can be found using the slope-intercept form of a line, y = mx + b, where m is the slope and b is the y-intercept.
To find the slope (m), you can use the formula: m = (change in y) / (change in x)
For the points (15, 8) and (16, 9), the change in y is 9 - 8 = 1 and the change in x is 16 - 15 = 1, so m = 1/1 = 1.
To find the y-intercept (b), you can use one of the points and the slope to solve for b. For example, using the point (15, 8), substitute x = 15 and y = 8 into the equation y = mx + b, and solve for b:
8 = 1 * 15 + b
8 = 15 + b
b = 8 - 15
b = -7
So, the equation from the relation is:
y = x + (-7)
y = x - 7
