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

Answer 1

The correct equation of this equation is

y = x - 1 (because our slope is positive so the 3 rd option cancelled here)
( and then we know y = mx + b is basic form so 2nd option cancelled out)
