The first option

you read the graph from left to right so x is increasing. If you look at y, it's decreasing.

for each y-value that decreases by 0.5, x-values increase by 1

The first option is correct, As the x- value increases by 1, the y-value decreases by 1/2; the x-intercept is -1.

What is a function?

A function is defined as a relation between the set of inputs having exactly one output each.

we can from the graph from left to right is that x is increasing. If you look at y, it's decreasing.

And for each y-value that decreases by 0.5, x-values increase by 1.

Thus, As the x- value increases by 1, the y-value decreases by 1/2 ; the x-intercept is -1.
