Answer: y= -2x - 4

Step-by-step explanation:

This is a straight line, so it can be expressed by y = mx + c.

Here c is y-intercept, which means where line cuts the y-axis. We can see from the graph that the line cuts the y-axis at -4.

So, c = -4.

m is slope.

Use slope formula to find m.

m = ( -4 - 0 ) / ( 0 -(-2))

m = -4 / 2

m = -2

Now put values into this equation

y = mx + c

y = -2x - 4
