Write the equation of a straight line that passes through the point (3,1) and is parallel to the line y=2x-1

Mathematics

velikii [3]2 years ago

Answer:

Step-by-step explanation:The new line will be parallel to the line represented by y =2x +2

The equation y = 2x + 2 is written in slope- intercept form (i.e. y=mx + b) where m represents the slope.  So the slope of this line is 2.   A line parallel to y = 2x + 2 will have the same slope.  This means the slope of the new line will also be 2.  

To determine the equation of the new line, we can use the given point  to find the y intercept of the new line:

y = 2x + b

Use x = -1 and y =3 to find b (or the y intercept ) of the new line:

3 = 2 * (-1) + b

3= -2 + b

b=5

Therefore, the equation of the line passing thru (-1,3) with the same slope as that of y = 2x + 2 will be:

 

 

y = 2x + 5

Which statement is true about the congruent triangles below? URGENT
VARVARA [1.3K]

Answer:

LN = HJ

Step-by-step explanation:

If you look at the two triangles, you will see each side has a different number of lines on them. Each set of lines corresponds to the same set of lines on the other triangle.

So since side IH has one line the side on the other triangle with one line would be congruent. So that would be line ML.

Also if there are not lines on every side then you could identify the triangle by the red square in the corner meaning that that is a right angle (90 degrees.)

Question in photo too lazy to solve lol​
Tamiku [17]

The value of 3centimeters to kilometers is 0,00003 km

<h3>Converting centimeters to meters</h3>

In order to convert centimeters to kilometers, we will use the conversion factor below.

100cm = 1m

1000m = 1km

Given 3cm

3cm = 3/100 m

3cm = 0.03m

Convert to km

Since 1000m = 1km

0.03m = 0.03/1000

0.03m = 0.00003km

Therefore the value of 3centimeters to kilometers is 0,00003 km
