Question

Find the equation of the line below. Arrange your answer in the form y = mx + b, where b is the constant.

Answer 1

m is your slope, b is your y intercept.

what is the slope of this line?

Answer 2

you find your slope (m) by looking at the rise over run. This means how much your line changes from one coordinate to another. So...
you rise is -1 and your run (sideways) is 1
so your slope=-1
b=where your line crosses the y axis, this would be at 0, so your equation would be
y=-1x+0 or just y=-1x
