Question 253622: For the equation y-3=7/13(x-4) is the slope 7/13 because when you do basic moves & then distribute you get y=7/13x-(4)7/13. The 7/13 is next the x and whenever you have a y= equation you can always say that the slope is always going to be next to the x but only in an y= equation. So is the slope 7/13

Question 253977: I don't know how I can show a graph on here, but I have a math problem that
shows a triange RST graphed on a coordinate grid.
The best I can do is tell what the points of the triangl are
R is (-5, -2)
S is (-2, -6)
T is (-6, -5)
Now
Part A
On the coordinate grid above, graph R'S'T, the image of triange RST after
a translation of 8 units to the right.
What I believe I have to do is take the point of S (-2, -6) which is the
point closest to the right in the grid and just count over 8 units.
That would mean that S would be be (6, -6). Then I would move the T
to the new position of (2, -5). Finally, the R would be at the new location of
(3, -2).
Is this right?
Part B asks this question.
How do the size and shape of R'S'T' compare with the size and shape of tri RST?
I think that the size and shape would remain the same after a translation of
8 units to the right.
Am I correct?
Part C
On the coordinate grid, I then have to graph R''S''T'', the image of R'S'T
after a reflection over the x axis.
I know that my triange would be in the upper right quadrant. I know that
it would flip over the line so that it would be a reflection. How can
I determine the coordinates of the vertices for the R''S''T'' final triangle.
I'm trying my best on this one. I know that it is alot of information, but
I hope someone can please help me.

she was learning ax(squared) + bx + c = y, which she understands.
However she was given
vertex (2, -3)
contains points (-1,-12)
y-k=a(x-h)squared
she has to find "a"
then plug in to the vertix form to find the ax form
