Answer:
y = 0.5x
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 0.5x - 2 ← is in slope- intercept form
with slope m = 0.5
Parallel lines have equal slopes, thus
y = 0.5x + c ← is the partial equation
To find c substitute (- 2, 1) into the partial equation
- 1 = - 1 + c ⇒ - 1 + 1 = 0
y = 0.5x + 0 , that is
y = 0.5x ← equation of parallel line
Answer:
25, -25
Step-by-step explanation:
This is the answer. It's simple. Just think of the two lines next to the number and that can be -25 and 25.

- <em>You would need fewer the unit</em><em><u> </u></em><u>kilometer (km) </u><em>to measure a tree.</em>
Explanation:
In the internet you can find that the greatest height of a tree is aobut 115 meters.
Thus, you would never expect to find a tree measuring kilometers or miles.
If you used kilometers as unit, the measure of the tallest tree woul be about 0.115 km (115 meter divided by 1,000).
Most of the trees meausre in the range of 1 to 20 meters. That would be 0.001 km to 0.020 km.
Thus, kilometer is not a unit that you would need to measure a tree. You'd rather use centimeters, when the tree is small, and meters for most of the trees. You may also use feet, since 1 meter is about 3.28 feet, or even yards, since 1 yard is equal to 3 feet.
If y = 0.75 when x = 0.5, set up a proportion -
0.75:0.5
x:3
Since you have to multiply 0.5 by 6 to get 3, multiply 0.75 by 6 to get your answer: y = 4.5 when x = 3.
Answer:
Step-by-step explanation:
3(b-4)=5b-2
distribute first!
3b-12=5b-2
10=2b
b=5
