help me plz i have been trying to figure it out forever

Answer:
y=3x-4
Step-by-step explanation:
The slope of the line is 3/1, 3 being the rise and 1 being the run. That's how you know that 3 is always going to be multiplied by x.
The -4 part is found by seeing where the line intersects with the y axis. Since the line crosses the y axis at -4, the equation will include -4.
Answer:
y+1=3(x-1)
Step-by-step explanation:
1. find slope
m=3
2.plug the given points and the slope to the point slope formula
point slope formula: y-y1=m(x-x1)
y-(-1)=3(x-1)
y+1=3(x-1)
