Answer:
point-slope equation: y + 6 = -4 ( x - 3 )
slope-intercept equation: y = -4x + 6
Explanation:
point-slope equation format:

slope-intercept equation format:

---------------------------------------------------------------------------------------------
coordinates: (3,-6) and (5,-14)
find slope using:

:

:

: -4
point-slope equation:
y - -6 = -4 ( x - 3 )
y + 6 = -4 ( x - 3 )
slope-intercept equation:
y + 6 = -4 ( x - 3 )
y = -4x + 12 - 6
y = -4x + 6
