Question

The slope of the line is 1, and the y intercept is -1. What is the equation of the line written in slope intercept form?

Y=x-1
Y=1-x
Y=-x-1

Answer 1

A. Y=x-1

Slope-intercept form is written: y=mx+b

M: Slope

B: Y-Intercept

Answer 2

Answer:
`y=x-1`

Explanation:

The equation of a line in slope-intercept form is given by :-

`y=mx+c` (1)

, where m = slope pf line.

c= y-intercept.

Given : Slope of line = 1

Y-intercept = -2

So , put m= 1 and c= -1 in equation (1) , we get

`y=(1)x+(-1)`

`\Rightarrow\ y=x-1` [∵ (+)(-)=(-)]

Hence, the equation of the line written in slope intercept form :

`y=x-1`
