Question

What is the equation of the blue line ?

Answer 1

Answer:

y=3x-1

Step-by-step explanation:

y=mx+b

m=3/1 --> 3(rise over run)

b=-1

y=3x-1

Answer 2

Rise over run. Or I believe. Like If I chose (-1,2) and (0,-1)  the rise or in this case since the line is going down, if I move down 4 units. I am one unit to the left of (0,-1) so 4/1 so rise/run
