Answer:
D. 12/27
Step-by-step explanation:
Ratios are just like fractions
12 ÷ 3 = 4
27 ÷ 3 = 9
4/9 is 12/27 simplified by 3

Answer:
Printer
Step-by-step explanation:
Printer is not an examples of input.
If a device is putting data into the computer in the form of text, sound, images, button presses etc. then it is an input device, if the device is outputting things from the computer such as sound, movement, printing, images etc., then it is an output device.
Answer:
y = -2x + 9
Step-by-step explanation:
Using the slope intercept equation y=mx+b, we can see that the slope of the line parallel to y = -2x + 7 is -2.
m = -2
Use the point slope formula y - y1 = m(x - x1) to find the line that runs through (4,1)
y - 1 = -2(x - 4)
Simplify
y - 1 = -2x + 8
y = -2x + 9
You can check your answer by putting in the point and seeing if the equaiton is true
1 = -2(4) + 9
1 = -8 + 9
1 = 1
True
