Answer:
B. -21a-15
Step-by-step Explanation:
Answer:
y=3x+5
y=-2x-1
y=-4x
y=1/2x+2
Step-by-step explanation:
These are linear functions(y=mx+b). m stands for the slope and b stands for the y intercept. After plugging in your slope, you use the coordinates they give you to find the y intercept. To find the y intercept plug in the y coordinate into the y in y=mx+b, and plug in the x coordinate into the same equation.

Hope my explanation made sense! I suck at explaining things lol.
Answer:
The laser printer will have depreciated to $1487.5
Step-by-step explanation:
The cost price is $3400 and at a depreciation rate of 12% annually
then if it is used for 3 years, it would have depreciated
(3400 × 12 × 3)/100
= 34 × 12× 3
= $1912.5
Therefore the new price value will be
$3400 - $1912.5 = $1487.5
Answer:
1
Step-by-step explanation:
Slope = change in y / change in x
Y-values: 9 and 2
x-values: 3 and -4
Change is the difference
9-2)/(3- (-4)) = 7/7 = 1
