You can graph that by looking at the y-intercept first. That's where you start to put a point in the coordinate plane or graph.

So go down 1 below 0.

Next, look at the slope.
We know that y = -2x - 1 is in slope intercept form (y = mx+b)
So -2 is our slope. It will be -2/1 because we need a fraction to graph the rise over run and all whole numbers can be a fraction by making 1 as their denominator.

Look at the attachment.

Starting from -1 (y-intercept), go down 2 (-2) then right 1 (1).
To complete the line above, keep the same value and reverse their sign/symbol. So -2/1 will be 2/-1. It goes up 2 then left 1.

I hope you understand and find this answer the most helpful! :)

John likes to watch the birds in her yard. One morning, she noticed that there are twice as many Robbins as Blue Jays. She count

Degger [83]

We can write an equation to solve this:

Let x represent amount of Blue Jays.

2x + x = 21

We can simplify the equation:

3x = 21

Divide both sides by 3 to isolate x variable:

x = 7

Therefore, 7 Blue Jays.
