Y=-2x+5
The standard form is y=mx+b, since m is the slope you would put -2 in substitute for it and since (0,5) has a zero as the x and a number as the y that gives you the b which is the y-intercept.

Answer:
C.
Step-by-step explanation:
The minus sign (of the multiplier -1/3) changes the direction of z by 180°. The magnitude of the multiplier 1/3 reduces the magnitude of the product to 1/3 that of z. The graph that has these characteristics is graph C.
