The values that complete the residual table a, b, c, d are as follows:
- a = 14.8, b = 0.1,
- c = 9, d = -1.1
What is the equation of a straight-line graph?
A straight-line graph takes the form y = mx + c, in which (m) refers to the gradient, (y) is the intercept, and (c) is the starting value when (x) is zero.
So, from the given information:
- y = -2.9x + 17.7 --- (1)
So, to estimate the value of (a) in the table, we have to replace (y = a) and (x = 1) in equation (1).
i.e.
- a = -2.9(1) + 17.7
- a = 14.8
To estimate the value of (b), we need to subtract the given value(12) from the predicted value (11.9)
- b = 12 - 11.9
- b = 0.1
To estimate the value of (c), we need to replace (y = c) and (x = 3) in equation (1).
- c = -2.9(3) + 17.7
- c = -8.7 + 17.7 = 9
To estimate the value of (d), we need to subtract the given value and predicted value.
- d = 5 - 6.1
- d = -1.1
