Question

Write an equation of the line that passes through the point (-1, 4) and has the slop of -1.

Answer 1

y = -x + 3.

Explanation:

Use the point-slope form of the equation of a straight line.

y - y1 = m(x - x1)
So, here we have:

y - 4 = -1(x - (-1))

y - 4 = -1(x + 1)

y - 4 = -x - 1

y = -x + 3.
