To find the equation of the linear function that models the relationship shown in the table, we first need to calculate the slope (m) using the two points given (11, 58) and (20, 103).
m = (y2 - y1) / (x2 - x1)
m = (103 - 58) / (20 - 11)
m = 45 / 9
m = 5
Now that we have the slope, we can use one of the points to find the y-intercept (b). Let's use point (11, 58).
y = mx + b
58 = 5(11) + b
58 = 55 + b
b = 58 - 55
b = 3
Therefore, the equation of the linear function is y = 5x + 3.
m = (y2 - y1) / (x2 - x1)
m = (103 - 58) / (20 - 11)
m = 45 / 9
m = 5
Now that we have the slope, we can use one of the points to find the y-intercept (b). Let's use point (11, 58).
y = mx + b
58 = 5(11) + b
58 = 55 + b
b = 58 - 55
b = 3
Therefore, the equation of the linear function is y = 5x + 3.

To find the equation of the linear function that passes through the points (-3, -1) and (2, 4), we first need to calculate the slope (m) using the two points.
m = (y2 - y1) / (x2 - x1)
m = (4 - (-1)) / (2 - (-3))
m = 5 / 5
m = 1
Now that we have the slope, we can use one of the points to find the y-intercept (b). Let's use point (-3, -1).
y = mx + b
-1 = 1(-3) + b
-1 = -3 + b
b = -1 + 3
b = 2
Therefore, the equation of the linear function is y = x + 2.
m = (y2 - y1) / (x2 - x1)
m = (4 - (-1)) / (2 - (-3))
m = 5 / 5
m = 1
Now that we have the slope, we can use one of the points to find the y-intercept (b). Let's use point (-3, -1).
y = mx + b
-1 = 1(-3) + b
-1 = -3 + b
b = -1 + 3
b = 2
Therefore, the equation of the linear function is y = x + 2.
