Answer:
Step-by-step explanation:
The Domain of a function is the x value, and the Range of a function is the y value. For example, in the ordered pair (9,4) the Domain is 9, or the x value, and the Range is 4, or the y value. So to find the Domain and Range, write ordered pairs for each plotted point on your graph (the dot at the end of each line) and then go through and identify the Domain and Range from there. When you list them, write the numbers in numeric order from least to greatest. Hope this helps!
A) parallel, same slope
Y = 3x + b
9 = 3(5) + b
9 = 15 + b, b = -6
Equation: y = 3x - 6x
B) y = -7x + b
11 = -7 + b, b = 18
Y = -7x + 18
c) y = 9x + b
-16 = 18 + b, b = -34
d) y = -x + b
9 = 2 + b, b = 7
Y = -x + 7
