please help: What is the equation of a line parallel to -5x + y= 2 that passes through the point with coordinates (-2, 1)?
weqwewe [10]

Answer:

  • y = 5x + 11 or -5x + y = 11

Step-by-step explanation:

<u>Given line:</u>

  • -5x + y = 2

<u>In slope-intercept form:</u>

  • y = 5x + 2

<u>The parallel line has the same slope and will look as:</u>

  • y = 5x + b

<u>This line passes through the point (-2, 1), substitute:</u>

  • 1 = 5*(-2) + b
  • b = 1 + 10
  • b = 11

<u>So the line is:</u>

  • y = 5x + 11

or

  • -5x + y = 11

3. The average distance from the sun to the planet Mercury is about 58,000,000 km. The diameter of a human hair is about 0.0025
zalisa [80]

Answer:

Distance of Sun and Mercury = 58,000,000 km.

In Scientific notation, it would be: 5.8 × 10⁷ Km

Diameter of a human hair = 0.0025 cm

In scientific notation, it would be: 2.5 × 10⁻³ cm

Before Comparison, we need to bring centimeter to Kilometers or vice-versa, so we can easily calculate then, here, we will go from cm to Km.

2.5 × 10⁻³ × 10⁻⁵ Km = 2.5 × 10⁻⁸

Now, we can compare the values, 

5.8 × 10⁷ Km > 2.5 × 10⁻⁸

[ reason. - power of smaller number is in negative, it means, it is denominator, which would be very small as compared to other ]

What is the solution to this problem (1,3)(5,k) m=2
Mazyrski [523]

Answer:

The solution of given problem is k = 11

Step-by-step explanation:

<u>slope of given two points formula:-</u>

slope m = \frac{y_{2}- y_{1}  }{x_{2}-x_{1}  } .....(1)

Given points are (1,3) and (5,k)

given slope m = 2

now substituting m =2 and the given points are (1,3) and (5,k)

2 = \frac{k-3}{5-1}

on simplification we get solution

k-3 = 8

k = 8 +3

k = 11
