No one's been able to answer this yet and i have so much more homework left to do.
write the slope-intercept form of the equation of the line.
1. through: (4,-4) slope=0
2. through: (5,-4) slope= -1/3

For the first one, since the slope is 0 the line must be just a horizontal line that passes through the given point. The equation would be y=-4 because the y coordinate for the point is -4.

For the second problem, utilize y=mx+b, the parent equation for slope intercept form (m-slope, b-y intercept).

y=mx+b

-4=-1/3(5)+b

b=-2 1/3

equation: y=-1/3x - 2 1/3
