D) y=-4x-5
Let’s first write the equation for this
y=mx+b
Let’s now look at the y-intercept. This is where the line hits the y-axis. As you can see,this is on negative 5.
Let’s substitute that into the equation, where b goes.
y=mx-5
Now let’s look for m,the slope. We can see that it is negative, and from one point to another it goes up 4 and over 1 to the left. This makes the slope -4. Let’s substitute that into m.
y=-4x-5 which is c.
