Question

The slope of the line below is 2. Which of the following is the point-slope form of the line? the x is 1 and the y is -1

Answer 1

The point slope form would be y+1=m(x-1)

Answer 2

Answer:

$(y+1)=2(x-1)$

Step-by-step explanation:

We have been given that the slope of a line is 2 and point (1,-1) in on our given line. We are asked to write the equation for our given line in point-slope form.

Since we know that point-slope form of an equation is: $(y-y_1)=m(x-x_1)$, where

m = Slope of line,

$(x_1,y_1)$ = Coordinates of the given point on line.

Upon substituting our given values in point-slope form of equation we will get,

$(y--1)=2(x-1)$

$(y+1)=2(x-1)$

Therefore, the equation $(y+1)=2(x-1)$ represents our given line in point-slope form.
