Answer: C. Substitute a value of x into the equation of a regression line and solve for y
Step-by-step explanation: To predict y values using equation of the regression line, a given value of x is substituted into the equation as there are only two unknowns in the whole regression equation, which are the x value ( independent variable) and the y value (the dependent or predicted variable).
The regression equation is usually of the form:
y = mx + c (linear regression)
Where y = predicted or dependent variable
m = slope or gradient of the regression line
x = independent variable
c = intercept of the line (where it cross the y-axis)
Answer:
3x - 5 = 10 x
The answer is:
Step-by-step explanation:
3x - 5 = 10x
First, Please, Add 5 to both sides, Which would be:
3x - 5 + 5 = 10x + 5
Second, Please, Simplify your answer, Which would be:
3x = 10x + 5
Third, Please, Subtract 10x from both sides, Which would be:
3x - 5 = 10x = 10x + 5 - 10x
Forth, Please, Simplify your answer, Which would be:
-7x = 5
Fifth, Please, Divide both sides by -7, Which would be:
Last and Finally, Simplify your answer, Which would be:
I hope I helped :)
