A line passes through the points (0, 2) and (2, 10). What is its equation in slope-intercept form?
levacccp [35]

Answer:

  • y = 4x + 2

Step-by-step explanation:

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

  • y = mx + b, where m is the slope, b is the y-intercept

<u>Find the slope using given points:</u>

  • m = (10 - 2)/(2 - 0) = 8 / 2 = 4

<u>The y-intercept is given with point (0, 2):</u>

  • b = 2

<u>The line is:</u>

  • y = 4x + 2

What is y greater then or equal to 2x on a graph
Juliette [100K]

Answer:

The minimal number for the objective function P =20x+16y is: 780

The value of x then is: 15

and the value of y then is : 30

Step-by-step explanation:

We are given a system of inequalities as:

y is less than or equal to 2x

i.e.          y ≤ 2x--------(1)

x + y is greater than or equal to 45

i.e.      x+y ≥ 45  ------------(2)    

and    x is less than or equal to 30.    

i.e.               x ≤ 30 -----------(3)    

On plotting these inequalities we get the boundary points as:

        (15,30) , (30,60) and (30,15)    

( Since, the optimal solution always exist at the boundary point )

The optimal function is given by:

 Minimize  P = 20x+16y

Hence, at (15,30) we get:

P= 780

at (30,60) we get:

 P= 1560

at (30,15) we get:

P= 840

This  means that the minimal value of the function is 780

and the value exist at (15,30)
