Write the equation of a line which has a slope of -1 and passes through the point (-2, -3).
:
Use the point/slope form, y - y1 = m(x - x1), where
m = -1
x1 = -2
y1 = -3
:
y - (-3) = -1(m - (-2))
minus a minus is plus
y + 3 = -1(x + 2)
distribute the -1
y + 3 = -1x - 2
subtract 3 from both sides
y = -x - 2 - 3
y = -x - 5 is the equation of a line with a slope of -1, passing thru -2,-3
:
:
You can confirm this, replace x with -2 and find y
y = -(-2) - 5
y = 2 - 5
y = -3
