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:

Given line:

-5x + y = 2

In slope-intercept form:

y = 5x + 2

The parallel line has the same slope and will look as:

y = 5x + b

This line passes through the point (-2, 1), substitute:

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

So the line is:

y = 5x + 11

-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:

slope of given two points formula:-

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

$k-3 = 8$

$k = 8 +3$

$k = 11$
