Which of the following is the equation of a line that passes through the points (1,6) and (2,1)
anastassius [24]

Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

To calculate m use the slope formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (1, 6) and (x₂, y₂ ) = (2, 1)

m = \frac{1-6}{2-1} = - 5, hence

y = - 5x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (1, 6), then

6 = - 5 + c ⇒ c = 6 + 5 = 11

y = - 5x + 11 → A

Using the formula A = 6s2, solve when s = 2?
rosijanka [135]

Answer:

When s=2, A=24

Step-by-step explanation:

We are given the formula A = 6s^2

We need to solve and find value of A , when s=2

So, putting value of s in the given formula we can find value of A

The formula given is:

A=6s^2\\Put\:s=2\\A=6(2)^2\\A=6(4)\\A=24

So, by putting s= 2, We get A=24

But he charges 3$ to mow a lawn.

So, he needs to mow 11/3= 3.66... lawns

The number of lawns can not be decimal. So, let's round to next whole number as 4.
