Find the equation of the line passing through the points (2, 1) and (5, 10).​
Vedmedyk [2.9K]

The equation : y=3x-5

<h3>Further explanation </h3>

Straight-line equations are mathematical equations that are described in the plane of cartesian coordinates

General formula

y-y1 = m(x-x1)

or

y = mx + c

Where

m = straight-line gradient which is the slope of the line

x1, y1 = the Cartesian coordinate that is crossed by the line

c = constant

The formula for a gradient (m) between 2 points in a line

m = Δy / Δx

  • Gradient

\tt \dfrac{10-1}{5-2}=3

  • Equation

\tt y-1=3(x-2)\\\\y-1=3x-6\\\\y=3x-5

What best describes the bonding in a carbon dioxide molecule?
gogolik [260]

Answer:

B. Carbon shares 2 pair of electrons with each oxygen.

Explanation:

  • Carbon dioxide is formed from combustion reactions, which involves a reaction between carbon and oxygen gas.
  • Carbon dioxide molecule is formed from one carbon atom and two oxygens. As an element, carbon only has 4 outer shell electrons and oxygen 6.
  • The two atoms require to gain electrons to achieve a stable configuration; carbon require to gain four electrons and oxygen requires two electrons.
  • Double covalent bonds form between the atoms, where two electrons from each atom are shared making 4 bonding electrons in total.

Hope it helped!
