which of the following equation represents a linear function a. f(x) =6x-3 b. f(x) = 7x(x+1) c. f(x) = x2+3x2 d. f(x) = x2(x-3​

a

Step-by-step explanation:

b, c, d are all x2 (a real linear equation does not have square or it will become Quadratic equation )

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
