Math Problem Statement

Graph the line through the given point with the given slope.

(0, 2), m = - 5

Solution

To graph the line that passes through the point (0,2)(0, 2) with a slope of m=5m = -5, we can follow these steps:

Step 1: Use the point-slope form of the equation of a line.

The point-slope form is given by: yy1=m(xx1)y - y_1 = m(x - x_1) where (x1,y1)(x_1, y_1) is the point on the line, and mm is the slope.

Here, (x1,y1)=(0,2)(x_1, y_1) = (0, 2) and m=5m = -5. Substituting these values into the formula:

y2=5(x0)y - 2 = -5(x - 0)

Simplify:

y2=5xy - 2 = -5x y=5x+2y = -5x + 2

Step 2: Identify key points on the line.

  • The y-intercept is (0,2)(0, 2) because when x=0x = 0, y=2y = 2.
  • From the slope m=5m = -5, this means that for every 1 unit increase in xx, yy decreases by 5 units (since the slope is negative).

Step 3: Plot the graph.

You can now plot the points on the coordinate plane and draw the line:

  1. Plot the point (0,2)(0, 2).
  2. From this point, move 1 unit to the right (increase xx by 1) and 5 units down (decrease yy by 5) to plot another point at (1,3)(1, -3).
  3. Draw a straight line through these points.
