Question

What is the equation of the line that passes through the point (- 1, - 5) and has a slope of -1

Answer 1

y = -x - 6

Explanation:

Slope = m = -1

Equation of line: y = mx + b

y = - x + b

Plugin x = -1 and y = -5 in above equation

-5 = -(-1) + b

-5 = 1 + b

-5 - 1 = b

b = -6

Equation of the line: y = -x - 6
