Answer:

see below

Explanation:

Our equation is y = 1/2x - 1. This mirrors our standard linear parent function of y = mx + b.

m is the slope and b is the y-intercept.

From this, we can see that

m = 1/2

and

b = -1.

The first point given is the y-intercept because with y-intercepts, we know the coordinates right away. A y-intercept's coordinates will always have an x-value of 0. This allows it to lie on the y-axis, hence the name. Our y-value of the coordinates is given with the b value of the equation. Therefore, by simply looking at the end of the equation, we know our first point.

Hope this helps!
