Please answer!! Which of the following is the equation of a line in slope-intercept form for a
line with slope = 1 and yintercept at (0, -1)?

A. y= 4x+1
B. y= 1x-1
C. y=-x-1
D. y= 4x-1

Hi there!

Recall that the equation of a line is:

y = mx + b, where:

m = slope

b = y-value of the y-intercept.

We are given that the slope is 1 and the y-intercept is -1, so:

m = 1

b = -1

The correct equation is B. y = 1x - 1

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
