Question

Answer thanks, show how you got the answer.

Answer 1

Y = 4X - 6

Explanation:

Slope of linear equation = change in Y / change in X

As Y is changing +4 units, with change in X +1 units. [ -6 - (-2) ] / [ 1 - 0 ]

So, slope = 4

Y = A + BX

Y = A + 4X , as B = slope & A = intercept

Putting values of X & Y (0,-6)

-6 = A + 4 (0)

A = -6

Hence, Equation : Y = 4X - 6
