Question

The slope of a 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

Is it the first one?

Answer 1

The slope-intercept form: y = mx + b

m - slope

b - y-intercept

We have: m = 1 and b = -1. Substitute:

y = 1x - 1

Answer: y = x - 1
