What is the slope of -y=-x+6
Katarina [22]

<u>Answer:</u>

  • m = 1
  • b = -6

<u>Step-by-step explanation:</u>

We know that:

  • -y = -x + 6
  • y = mx + b

First, we need to change the 'y' sign.

  • => -y = -x + 6
  • => y = x - 6

Now, let's compare both of the equations to find slope.

  • => (y = x - 6) = (y = mx + b)

We can see that the slope is 1 and the y-intercept is -6.

<u>Conclusion:</u>

Therefore:

  • m = 1
  • b = -6

Hoped this helped.
