* (10) If the point (3,a) lies on the graph of the linear relation
described by the equation y=9-4%, determine the
value of a.

Respuesta :

Answer:   a = -3

Explanation:

The point (3,a) means that x = 3 and y = a pair up together

Plug in those values and compute 'a'

y = 9-4x

a = 9-4(3)

a = 9-12

a = -3

The point (3, a) updates to (3, -3)

The point (3, -3) is on the line y = 9-4x
