Can you please graph the following function:y=3x-1

To graph a linear function you need to determine two points of said function, plot them in the coordinates system and link them by a line.

The most easy point to find is the y-intersect. This is the value of y when x=0

Replace it in the equation:

\begin{gathered} y=3x-1 \\ y=3\cdot0-1 \\ y=-1 \end{gathered}

The y-intersect is (0, -1)

To determine the second point you have to select any value of x of your choise and replace it in the formula to determine the y-coordinate.

For example: x=4

\begin{gathered} y=3x-1 \\ y=3\cdot4-1 \\ y=11 \end{gathered}

The coordinates for the second point are (4, 11)

Now plot both points in the coordinate system and the line.

Answer:

The length of river frontage for each lot are 96.55 ft. 98.85 ft, 101.15 ft and 103.45 ft.

Step-by-step explanation:

See the attached diagram.

The river frontage of 400 ft will be divided into 84 : 86 : 88 : 90 for each lot as AP, BQ, CR, DS and ET all are parallel.

Therefore, PQ : QR : RS : ST = 84 : 86 : 88 : 90 = 42 : 43 : 44 : 45

Let, PQ = 42x, QR = 43x, RS = 44x and ST = 45x

So, (42x + 43x + 44x + 45x) = 400

⇒ 175x = 400

⇒ x = 2.2988.

So, PQ = 42x = 96.55 ft.

QR = 43x = 98.85 ft.

RS = 44x = 101.15 ft and  

ST = 45x = 103.45 ft

B). 2⁄3 × 1⁄5 × 4⁄7 ==>  2/3  *  1/5 * 4/7  ====>  8 / 105 ===> (Decimal: 0.07619)


C). 3⁄5 × 10⁄12 × 1⁄2 ===> 3/5 *  10/12 ===> 30/60 ===>  1/2 ==> 1/2 *  1/2 ===> 1/4 (Decimal:      0.25)


D). 4⁄9 × 54 ===>  4 *  54/ 9.1  ====>  216/9 ===> 24/1   ===>  24


E). 20 × 3 1⁄5 ===> 20 * 16/ 1.5  ====>320/5 ====>  64/1  =====> 64


F). 11 × 2 7⁄11 ====>  319/11  ====> 29/1    ======>  29


G). 5 1⁄3 × 5 1⁄8 ==> 16/3 * 41/8 ==> 656/24 ==> 82/3 ==> 27 1/3 ==> (Decimal:  27.33333)


H).  10 2⁄3 × 1 3⁄8  ===>  32/3 *  11/8 ===> 44 / 3   ===>  14 2/3  ==>  (Decimal: 14.666667)
