Answer:
The rule is as follows:
x'=5*x
y'=5*y
Step-by-step explanation:
Each coordinate gets scaled by a factor of 5.
For example:
R(-2,0) --> R'(-10,0) [-2-->5*(-2), 0-->0]
and similarly with the other points S, T, and U
1. In algebra, a function is an equation that has only one answer for y for every x present.
2. The set (3,4) (4,5) (5,6) and (6,7), represents a function because when graphed, it forms a diagonal line. The <em>second</em> set of coordinates forms a non-linear "line." Furthermore, a way to test if something is a function or not is through the VERTICAL LINE TEST. If a vertical line can pass through the graphed line without touching it in two places at once, then it's a function. Vertical lines automatically fail this test; the second set of ordered pairs creates a vertical line.
3. The slope-intercept form of the correct line is y = 3/3x + 1. (y = mx + b)
4. The slope is -2 and the y-intercept is 6.
5. A horizontal line has a slope of 0 (Zero Slope) because it doesn't slope! A vertical line has an undefined slope because... it does.

Answer:
Y=7 and
X=9
Step-by-step explanation:
X+Y=16
X=2+Y
2+Y+Y=16
2+2Y=16
2Y=16-2
2Y=14
2Y/2=14/2
Y=7
X =2+Y
So X=9
