Which linear function represents the line given by the point-slope equation y minus 8 is equal to 1 half times open paren x minus 4 close paren ?
A
f of x is equal to 1 half x plus 4B
f of x is equal to 1 half x plus 6C
f of x is equal to 1 half x minus 10D
f of x is equal to 1 half x minus 12Distribute 1/2 across (x − 4): y − 8 = 1/2x − 2. Add 8 to both sides to get y = 1/2x + 6, so the linear function is f(x) = 1/2x + 6.
