Could someone please explain to me how to do this? I'm so confused.

Step-by-step explanation:

First the slope. The slope is the number before the x. First, is the slope positive or negative? To find this determine if the slope is negative or positive. If it’s positive, the line goes up. If it’s negative, the line goes down.

This slope is negative, so we know the line will go down.

Now the slope is 1/2

Slopes are rise/over or y/x

To find where to put the line, look at the y-intercept

The y intercept is the number that comes after the x in the equation. The y intercept in this problem is -3.

Y intercepts are where the line crosses the y-axis so find -3 on the y axis.

Now from there. Use the slope to make points.

First go down one and then go right two.

Now mark a point there and continue to do this with each point.

You go one down because the y value in -1/2 is 1 and you go right two because the x value is 2.
