The equation of the linear function represented by the table can be found by finding the slope (m) and the y-intercept (b).
To find the slope, we can use the formula:
m = (change in y) / (change in x)
For this table:
(change in y) = -3 - 10 = -13
(change in x) = 6 - 18 = -12
m = (-13) / (-12) = 13/12
To find the y-intercept, we can use the formula:
b = y - mx
Using the point (18, 10):
b = 10 - (13/12)(18) = 10 - (13/12)(3/2) = 10 - 13/8 = 67/8
Therefore, the equation of the linear function represented by the table is:
y = (13/12)x + 67/8

I apologize for the incorrect response. Let's re-evaluate the problem.
Given the points (18,10) and (6,-3), we can find the equation of the linear function using the slope-intercept form:
y = mx + b
The slope (m) can be determined using the formula:
m = (change in y) / (change in x)
(change in y) = -3 - 10 = -13
(change in x) = 6 - 18 = -12
m = (-13) / (-12) = 13/12
To find the y-intercept (b), substitute one of the points into the equation and solve for b. Let's use the point (18,10):
10 = (13/12)(18) + b
Multiply both sides by 12 to eliminate the fraction:
120 = 13(18) + 12b
120 = 234 + 12b
12b = -114
b = -9.5
Therefore, the equation of the linear function represented by the table is:
y = (13/12)x - 9.5
Given the points (18,10) and (6,-3), we can find the equation of the linear function using the slope-intercept form:

(change in x) = 6 - 18 = -12
m = (-13) / (-12) = 13/12
To find the y-intercept (b), substitute one of the points into the equation and solve for b. Let's use the point (18,10):
10 = (13/12)(18) + b
Multiply both sides by 12 to eliminate the fraction:

120 = 234 + 12b
12b = -114
b = -9.5
Therefore, the equation of the linear function represented by the table is:
y = (13/12)x - 9.5
