Answer:
17
Step-by-step explanation:
-(-17)= 17
A relation is a relationship between sets of values. In math, the relation is between the x-values and y-values of ordered pairs. The set of all x-values is called the domain, and the set of all y-values is called the range.
Answer:

Step-by-step explanation:
In the equation: 
x's can be simplified and y's can be simplified!
Always remember that for exponents, you subtract the powers when dividing
so for x: 15-8 = 7
for y: 9-3 = 6
so the final answer is: 
Answer:
0.2
Step-by-step explanation:
2/10=0.2
Answer:
Step-by-step explanation:
y = (-1/2)x + 4 is the equation of a straight line with y-intercept (0, 4) and slope -1/2.
To graph this, first plot the y-intercept (0, 4).
Recall that slope m = rise / run, and notice that the slope in this particular case is -1/2 = rise / run, or rise = -1 and run = 2.
Starting with your pencil point on (0, 4), move the point 2 units to the right (run = 2), arriving at (2, 4). Next, move your pencil point 1 unit down, to (2, 3).
Draw a straight line through (0, 4) and (2, 3).
