Answer:

y+1 = 3(x-1)


Step-by-step explanation:

We need to find the slope

We have one point (1,-1)  Another point is (2,2)

Slope = (y2-y2)/(x2-x1)

         = (2--1)/(2-1)

       = (2+1)/(2-1)

        = 3/1

The slope is 3

Point slope for of a line is given by

y-y1 = m(x-x1)

We are to use the point (1,-1)

y--1 = 3(x-1)

y+1 = 3(x-1)

Answer:

y + 1 = 3(x - 1)

Step-by-step explanation:

The given point is (1,-1) meaning that x1 = 1 and y1 = -1

The slope of this line is m = 3 because we go up 3 and over to the right 1 (eg: go from the point (1,-1) to (2,2) to see this in action)

Plug these three pieces of info into the point slope formula below

y - y1 = m(x - x1)

y - (-1) = 3(x - 1)

y + 1 = 3(x - 1)
