Question

Slope -1; y-intercept (0,1)

Answer 1

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0)

Since you know m = -1 and b = 1, you can plug it in:

y = mx + b

y = -1x + 1 or y = -x + 1

Answer 2

You should get: y=-x+1. The slope is -1, which is implied because the you don't need the one in front of the x.
