5^-3=0.008
1/2=0.5
0.5*0.008=0.004
5/0.004=1250
15:20
divide each by 5
3:4
to find the ratio of the area's we square the ratio's of the sides
3^3 : 4^2

Choice B
<span>T(x,y) -> (x-3, y+7)
</span><span>is usually i have seen them parametrically defined

About Slope - Intercept Form:
- y = mx + b
- m is the slope
- b is the y-intercept
About Standard Form:
- Ax + By = C
- A & B & C are integers
- A & B are both non-zero
- This form is good to use when wanting to find the x & y intercepts of a line
About Point - Slope Form:
- Y - Y1 = m (x -X1)
- Y1 & X1 is a point on the line
- The form allows you to identify the slope & the point on the line
Other Info:
- Remember, y comes before the x
- An ordered pair from your problem: (-3,1), -3 is x & 1 is y & x is before the y
- An ordered pair from your problem: (3,5), 3 is x & 5 is y & x is before the y
- For the graph, the vertical line is y
- For the graph, the horizontal line is x
Hope this information helps!!! :)
