The slope is
The y-intercept is
The slope of the table can be found by calculating the change in y divided by the change in x.
Change in y = 13 (last y value) - 7 (first y value) = 6
Change in x = 4 (last x value) - 1 (first x value) = 3
Slope = Change in y / Change in x = 6 / 3 = 2
Therefore, the slope of the table is 2.
To find the y-intercept, we can use the point-slope form of the equation of a line, y = mx + b, where m is the slope and b is the y-intercept.
Using the point (1, 7), we can substitute the values into the equation: 7 = 2(1) + b
Solving for b, we get:
b = 7 - 2
b = 5
Therefore, the y-intercept of the table is 5.
