Please help :(

What is the equation of the line that passes through the point (2,-6) and has a slope of -1?

Answer 1

y = -x - 4

Explanation:

Plug in the point and slope into the equation y = mx + b, and solve for b:

y = mx + b

-6 = -1(2) + b

-6 = -2 + b

-4 = b

Then, plug in b and the slope into y = mx + b

y = -1x - 4

y = -x - 4 is the equation of the line
