QuestionGraph the line given by the equation y=13x2y=-\frac{1}{3} x-2.

Studdy Solution

STEP 1

Assumptions1. We are graphing the line in a two-dimensional Cartesian coordinate system. . The equation of the line is given by y=13xy=-\frac{1}{3} x-.

STEP 2

The equation of the line is in the slope-intercept form y=mx+by=mx+b, where mm is the slope of the line and bb is the y-intercept. In this case, m=1m=-\frac{1}{} and b=2b=-2.

STEP 3

The y-intercept b=2b=-2 is the point where the line crosses the y-axis. This means our line crosses the y-axis at the point (0,2)(0, -2).

STEP 4

The slope m=13m=-\frac{1}{3} tells us how steep the line is. A slope of 13-\frac{1}{3} means that for every3 units we move to the right along the x-axis, we move1 unit down along the y-axis.

STEP 5

Starting from the y-intercept (0,2)(0, -2), move3 units to the right to x=3x=3, and then1 unit down to y=3y=-3. This gives us another point on the line, (3,3)(3, -3).

STEP 6

Plot the points (0,2)(0, -2) and (3,3)(3, -3) on the Cartesian plane.

STEP 7

Draw a straight line through the points (0,2)(0, -2) and (3,3)(3, -3). This line represents the graph of the equation y=13x2y=-\frac{1}{3} x-2.
