Answer: Predicted level of social skill will be 46
Step-by-step explanation:
For a linear regression; the general equation is in the form;
y = mx + c
Where is the predicted value or variable
m = slope or gradient (regression coefficient )
c = intercept which is constant (this is where the line of best for crosses the y-axis.
y = predicted value
x = independent variable
Given the following:
Regression coefficient (m)= 3
Regression constant (c)= 16
Score(x) = 10 (independent variable)
From:
y = mx + c
y = 3(10) + 16
y = 30 + 16
y = 46
Predicted level of social skill will be 46
Answer:
x - 2y - 8 = 0
Step-by-step explanation:
y + 2 = 1/2x - 2
y + 2 + 2 - 1/2x = 0
-1/2x + 4 + y = 0
-2[-1/2x + y + 4] = 0(-2)
x - 2y - 8 = 0
