A)m=2

B)m=5

C)m=-2

D)m=-5

Answer 3

ok

Answer 4

c. (using y=mx + b formula, m=slope)

Answer 5

Well, What about this?


The value, in dollars, of a particular KX37B computer is given by V = -412.48x + 6843, where x is the number of years the computer has been in existence


a.
-412.48 signifies the amount of depreciation in one year, and 6843 signifies the initial cost.
c.
-412.48 signifies the hourly cost of repairs, and 6843 signifies the cost of software.
b.
-412.48 signifies the number of computers owned, and 6843 signifies the cost of electricity.
d.
6843 signifies the amount of depreciation in one year, and -412.48 signifies the initial cost.

Answer 9

1. C.....(y = mx + b where m is the slope)
to find 5 ordered pair that will satisfy this equation, sub in any number for x and solve for y.

y = -2x + 5
lets make x = 0
y = -2(0) + 5
y = 5
so when x is 0, y = 5...so one solution is : (0,5)

now pick another number for x....lets let x = 1
y = -2x + 5
y = -2(1) + 5
y = -2 + 5
y = 3
so when x is 1, y is 3.....so another solution is (1,3)

you can find 3 more solutions by subbing in any number and solving for y.
