Question

I need a little help

Answer 1

Step-by-step explanation:

It looks Iike the equation is in slope intercept form

`y = mx + b`

m is the slope

b is the y intercept

Finding B is easy, it's just where X = 0. On this table, Y is 1 when X is 0.

Finding the slope. We'll take two different (X,Y) coordinates. Let's do the first two rows (0,1) and (1,-1)

Next we apply the slope formula. That being

`m = (y2 - y1)/(x2 - x1)`

So plugging that in

`= ( - 1 - 1)/(1 - 0)`

That gives you -2/1, also known as -2

Now that we have everything, we can put the forumla together

`y = - 2x + 1`

Where -2 is the answer that belongs in the [?]

Answer 2

y=-2x+1

Step-by-step explanation:

you can see that the x goes up by 1 every time. Y goes down by 2 every time, because 1-2=-1, -1-2=-3, etc. So the -2 goes in your m part of y=mx+b. Then you need to figure out what y is when x is 0, for your y-intercept, or your b part of y=mx+b. The picture makes it simpler, showing that when x is 0, y is 1. Therefore, 1 is your b part of y=mx+b. If you put it all together, it looks like this:

Y=-2x+1
