Question

What’s the answer to this

Answer 1

Answer:

A

Step-by-step explanation:

As you can see on the y side, it goes down by 4. On the x side, it goes up by 1. So, that means that the slope is -4/1, or -4. To find the y intercept, you do y-y1=m(x-x1). This is point slope form. Basically, you replace x1 for any value of x, and y1 for any value of y, but they have to be the same coordinate point. So you can use 0 and 3, or 1 and -1, but you cant use 0 and -1. Put it simply, the equation becomes y-(-1)=-4(x-1). When we simplify, it becomes y+1=-4x+4. When we simplify even further, it becomes y=-4x+3, which is the same exact answer as A
