Function k is a linear function with a slope of 1/2 that passes through the point (4,2). What equation represents Function K?

A. y = 1/2x

B. y = 1/2x + 1

C. y = 1/2x + 3

D. y = 1/2x + 4​

Respuesta :

Answer:

A. y = 1/2 x.

Step-by-step explanation:

Use the point-slope form of a linear (straight line) function:

y - y1 = m(x - x1)

m = 1/2, x1 = 4 and y1 = 2, so:

y - 2 = 1/2(x - 4)

y = 1/2x - 2 + 2

y = 1/2 x (answer)
