Answer 5

I am not good with function so I will do what I can.

2. y = -x - 7
slope(m) = -1
parallel lines have same slope
y = mx + b
slope(m) = -1
(1,79)...x = 1 and y = 79
now sub
79 = -1(1) + b
79 = -1 + b
79 + 1 = b
80 = b
your equation is : y = -x + 80
==================
4. f(x) = 7x - 1
The value of 7x - 1 when x is 12.
==================
5. value of horizontal line passing through (2,3)
horizontal line has a slope of 0 and is represented by y = a number.
so equation is : y = 0x + 3, or just y = 3
=================
8. f(n) = 9n + 32
=================
9. (-2,-3)...and slope of -6
y = mx + b
-3 = -6(-2) + b
-3 = 12 + b
-3 - 12 = b
-15 = b
equation is : y = -6x - 15
=================
I did what I could :)
