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.

A person walked 50 ft. to cross
mariarad [96]

Answer:

B) 40 ft

Step-by-step explanation:

Use the picture for a reference.

1. We can see the diagonal forms a triangle. Since the angles of a rectangle are right, we can use the Pythagorean Theorem to solve for x.

2. The Pythagorean Theorem

a^2 (a squared) + b^2 (b squared) = c^2 (c squared)

a = 30 ft (width)

b = x ft (unknown length)

c = 50 ft (diagonal)

3. Substitute in the values:

    30^2 + x^2 = 50^2

    900 + x^2 = 2500

    x^2 = 1600

    x = 40

The length of the field is 40 ft.
