Please help I need this today. What is the x and y intercept of the graph y=-1/2x+4?

Options are 1/2, -4, -1/2, 4, and 8.

x- intercept = 8

y- intercept = 4

Step-by-step explanation:

x int; y= 0

0 = - 1/2x +4

1/2x = 4

x = 4÷1/2

x = 8

y int; x = o

y = -1/2(0)+4

y = 4

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
