Can you please graph the following function:y=3x-1
KiRa [710]

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.

What is the slope of a line that is perpendicular to the line x = –3? –3 0 1/3 undefined
Elena L [17]

Answer:

slope = 0

Step-by-step explanation:

The line with equation x = - 3 is a vertical line parallel to the y- axis

A perpendicular line is therefore a horizontal line parallel to the x- axis

The slope of the x- axis is zero, hence the slope of the horizontal line is

slope = 0

Answer:

70 degrees

Step-by-step explanation:

Measure of arc ABC is 128 degrees, so measure of arc BC is 128-90 = 38 degrees.

Meausure of arc BCD is 102 + 38 = 140 degrees, so measure of angle A is 140/2 = 70 degrees
