Answer:

y = 2x + 4

Step-by-step explanation:

the equation of a line in point- slope form is

y = mx + c ( m is the slope and c the y- intercept )

here m = 2 and passes through point (0, 4 ) ⇒ c = 4

y = 2x + 4 ← equation of line

Answer:

y = 2x + 4

Step-by-step explanation:

General form of linear equation:  y = mx + c

where m is the gradient and c is the y-intercept

Given gradient = 2  

⇒  m = 2  

⇒  y = 2x + c

y-intercept is when x = 0

Given (0, 4), so y = 4 when x = 0

⇒ c = 4

⇒ y = 2x + 4

You use 4 gallons of water on 14 plants in your garden.At this rate, how much water will it take to water 35 plants?
Naddika [18.5K]

For this case we can make the following rule of three:

4 gallons --------------> 14 plants

x --------------------------> 35 plants

From here, we clear the value of x.

We have then:

x = (\frac{35}{14}) * (4)\\x = 10

therefore, 10 gallons are needed to irrigate 35 plants.

Answer:

it will take 10 gallons to water 35 plants
