Answer:
A
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-9)/(-3-2)
m=10/-5
m=-2
y=-2x+b
9=-2*-3+b
9=b+6
b=3
y=-2x+3
A
Answer:
See below
Step-by-step explanation:
1. Standard notation
4.2 × 10⁻⁴ m
A negative exponent indicates
- A number between 0 and 1.
- That the decimal point is shifted that number of places to the left.
4.2 × 10⁻⁴ tells you that the decimal number is 4.2, with the decimal point moved four places to the left.
The number becomes 0.000 42
.
2. Metres to millimetres

3. Measurements agree?
Yes, because both measurements are the same as 0.42 m.
4. More appropriate measurement
Most measurements should be expressed as a number between 0.1 and 1000, because most people aren’t particularly good at visualizing larger or smaller numbers.
Justin's measurement of 0.42 mm is more appropriate than Amanda's measurement of 4.2 × 10⁻⁴ m.
OK, So what I do first: How many times can this number go into 1?
1/4 goes evenly into 1 4 times.
Now how many wholes numbers are there? 2.
2*4=8
Now how many fourths are left over? 2.
Add them to 8.
10
10 is your answer.
