Write the equation 3x + y = -10 in the point-slope form * y - 10 = 3(x - 0)
y + 10 = 1(x - 0)
y + 10 = 3(x - 0)
y - 0 = -3(x + 10)

Step-by-step explanation:

You haven't specified what point to use.

For simplicity, I'll use the y-intercept, (0,-10)

slope of line = -3

point-slope equation for line of slope -3 that passes through (0,-10):

y+10 = -3(x-0)

which doesn't fit any of the choices!

i hope this is what you were looking for.
