Answer:
C) 8
Explanation:
Use the formula
Slope =
- any y value
- x value corresponding to y_1
similarly, you can pick y_2 and x_2 from the table.
Pick any two rows
Let's pick row 3 and 4
Slope =
=> 10/2
Slope = 5
Now formula
y = slope * x + intercept
y = 5x + intercept
intercept = y - 5x
Now take any row from the table and substitute above to calculate intercept
Taking row 3
intercept = 23 - 5 * 3
intercept = 8
