Choose the equation that matches the graph
a. y=*
b. y=-x
c. y = 4x
d. y = -4x

y = - 1/4 x

Step-by-step explanation:

Look for the slope of this graph.

Take for an example of a point. Let's take (-4,1) and (0,0)

Now let's see how many downs and rights needed to go from (-4,1) to the origin (0,0).

As you can see, it goes 1 down and 4 rights.

So now you know the slope of the line which mean you can choose one of the choices now.

1 down, means negative one (-1), will be a numerator of the slope fraction and 4 right, meaning positive four (4), will be a denominator of the slope fraction.

Note: This method is only available when you see two easy points to determine. In most cases you have to do the math using the slope formula.

Hope this helps
