Use the given conditions to write an equation for the line in point-slope form and slope intercept form.
Passing through (-4, 7) and (-6, 15)
Answer y - 7 = 4(x + 4) or y - 15 = 4(x + 6); y = 4x + 9
y - 7 = -4(x + 4) or y - 15 = -4(x + 6); y = -4x + 9
y - 7 = 4(x + 4) or y - 15 = 4(x + 6); y = 4x - 9
y - 7 = -4(x + 4) or y - 15 = -4(x + 6); y = -4x - 9
