Question

What is the standard form equation of the line passing through (1, –5) with a slope of –1

Answer 1

If the slope is -1, you know the equation is of the form y = -x+b.

Answer 2

So, now you only need to plug in the numbers from (1,-5).

Answer 3

Plugging in, we have -5 = -(1) + b. This gives b=-6.

Answer 4

So the equation is y=-x-6, so, in standard form, this is x+y=-6.

Answer 5

Okay?
