Answer:
B
Step-by-step explanation:
3n^2 + 3(3m^3 + 3n^3) =
= 3n^2 + 9m^3 + 9n^3
= 9m^3 + 3n^2 + 9n^3
Answer:
The point-slope form of the equation of a line is ...
y -h = m(x -k)
for a line with slope m through point (h, k).
Comparing this to the given equation, you see that ...
h = -2, m = 1, k = -4
The line has a slope of 1 and goes through the point (-4, -2). This information is useful for graphing.
__
You can also rearrange the equation to slope-intercept form by subtracting 2 from both sides.
y = x +2
This has a slope of 1 and crosses the y-axis at y=2. It graphs the same as the above.
