Question

Given the equation of a regression line as y = 1.2x - 3.4. What is y value when x is 5?

Answer 1

y = 1.2x - 3.4

By placing the value of x = 5 we get :

y = 1.2 × 5 - 3.4

y = 6 - 3.4

y = 2.6

Hence the value of y is = 2.6

Hey mate here we go

$y = 1.2x - 3.4 ...................(1)\: \: \: \: \: \\ where \: x = 5 \\ then \: we \: should \: put \: x \: value \: in \: \: equation \: 1 \\ now \: y = 1.2(5) - 3.4 \\ y = 6.0 - 3.4 \\ y = 2.6 \\ \\ i \: hope \: this \: will \: help \: u \\ mark \: me \: as \: brainliest$
