Question

Need to know how to graph this example y= -2x + 25. I know that y=mx+b. Just confused on how to get what they call plug in. Can someone explain please. Example how do I know x= 0 and X= 1

Answer 1

Here's an example
Y=5x + 10
if x is equal to 5 you would make it
Y=5(5)+10.
basically, just replace the x with what it's equal to.
