1) We have to find the slope of the linear function represented in the table.
If we already know it is a linear function we can take two points (x,y) from the table, like (0,13) and (2,14) and calculate the slope m as:
2) The y-intercept correspond to the value of y when x = 0.
From the table we can see that when x = 0, y is equal to 13.
Then, the y-intercept is b = 13.
3) Knowing the slope m = 0.5 and the y-intercept b = 13, we can write the equation of the line in slope-intercept form as:
Answer:
1) Slope m = 1/2
2) y-intercept b = 13
3) Equation: f(x) = 1/2*x + 13
