Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{ - 1 }}}}}

Step-by-step explanation:

Given, f( x ) = 2x - 3

Here, we assume the value of x as 1

Now, <u>Finding </u><u>f</u><u> </u><u>(</u><u> </u><u>1</u><u> </u><u>)</u>

\sf{f(1) = 2 \times 1 - 3}

Multiply the numbers : 2 and 1

⇒\sf{f(1) = 2 - 3}

Subtract the numbers : 3 from 2

⇒\sf{f(1) =  - 1}

Hope I helped!

Best regards!!

*27 POINTS PLEASE HELP*
EleoNora [17]

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.
