Look at the picture.
The point-slope form:
We have the points (-3, -3) and (2, 0). Substitute:
Answer:
point-slope form:
slope-intercept form:
standard form:
The answer would be the hundreds place
To find out you go from right to left.
For this problem you would start with 9
The 9 is in the units place
Then you go to 2
The 2 is in the tens place
Therefore the 3 is in the hundreds place
If you want to find out all the places to this problem here it is as follow:
4- ten thousands
5- thousands
3- hundreds
2- tens
9- units
Hope this helps! :3
Since you need the vertex, and knowing the vertex will tell you the axis of symmetry, it is convenient to put the equation in vertex form.
.. -x^2 -4x +1
.. = -(x^2 +4x) +1
.. = -(x^2 +4x +(4/2)^2) +1 -(-(4/2)^2) . . . . complete the square
.. = -(x +2)^2 +5
The vertex is (-2, 5).
The axis of symmetry is x = -2.
