y = -1/2 x + 1

Step-by-step explanation:

(-2, 2) and (4, -1)  are points of the linear function, that will be described as:

y = ax + b

setting x=-2, y=2:

2 = -2a + b, so b = 2 + 2a

setting x=4, y=-1:

-1 = 4a + b ⇒ -1 = 4a + 2 + 2a ⇒   -3 = 6a ⇒ a = -1/2, b = 1

y = -1/2 x + 1

where does the z at is it on the x axes or on the y axes any way if it is on the y axes put it horizontally and if it is on the x axes put it vertically
