To compute the slope of a segment, given its endpoints A(A_x,A_y),\ B=(B_x,B_y), you write

m_{AB} = \dfrac{A_y-B_y}{A_x-B_x}

Given this formula, you have the four slopes:

m_{AB} = \dfrac{A_y-B_y}{A_x-B_x} = \dfrac{-1-2}{-4+1} = \dfrac{-3}{-3} = 1

m_{BC} = \dfrac{B_y-C_y}{B_x-C_x} = \dfrac{2-1}{-1-5} = \dfrac{1}{-6} = \dfrac{-1}{6}

m_{CD} = \dfrac{C_y-D_y}{C_x-D_x} = \dfrac{1+3}{5-1} = \dfrac{4}{4} = 1

m_{DA} = \dfrac{D_y-A_y}{D_x-A_x} = \dfrac{-3+1}{1+4} = \dfrac{-2}{5} = -\dfrac{2}{5}

Now, two segments are parallel if they have the same slope. So, AB and CD are parallel, because they both have slope 1, but BC and DA are not parallel.

This means that ABCD is not a parallelogram, because in parallelograms the opposite sides are parallel.

How do you use graphs toslove a system of two linear equation
marysya [2.9K]

Answer:

A system of linear equations is a system made up of two linear equations. To solve the system of equations, you need to find the exact values of x and y that will solve both equations. One good way to do this is to graph each line and see where they intersect.

A recipe for casserole calls for 2 cups of rice. The recipe makes 6 servings of casserole. how many cups of rice will you need t
ss7ja [257]

You will need 3.333.... cups of rice to make 10 servings of casserole.

<u><em>Explanation</em></u>

The recipe which makes 6 servings of casserole, needs 2 cups of rice.

Suppose, you need x cups of rice for making 10 servings of casserole.

Now, the equation according to <u>the ratio of "cups of rice" to the "servings of casserole" </u>will be.....

\frac{x}{10}=\frac{2}{6}\\ \\ 6x= 2*10=20\\ \\ x=\frac{20}{6}=3.333.....

So, you will need 3.333.... cups of rice to make 10 servings of casserole.
