Question

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

Answer 1

y+1=3(x-1)

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)

Answer 2

y=3x-4

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.
