Math Problem Statement

Graph this line: y - 5 = (1/5)(x - 1).

Solution

Let's analyze the equation of the line provided:

y5=15(x1)y - 5 = \frac{1}{5}(x - 1)

This equation is in point-slope form, which is:

yy1=m(xx1),y - y_1 = m(x - x_1),

where mm is the slope, and (x1,y1)(x_1, y_1) is a point on the line. From the equation:

  • The slope (mm) is 15\frac{1}{5},
  • The point (x1,y1)(x_1, y_1) is (1,5)(1, 5).

Steps to Graph the Line:

  1. Plot the point (1,5)(1, 5) as given in the equation.

  2. Use the slope 15\frac{1}{5} (rise over run):

    • Rise = 11 (move up by 1 unit),
    • Run = 55 (move right by 5 units).

    Starting from (1,5)(1, 5), moving 5 units right and 1 unit up takes you to (6,6)(6, 6).

  3. Plot this second point (6,6)(6, 6).

  4. Draw a straight line through these two points.


Key Points to Plot:

  • (1,5)(1, 5) — starting point.
  • (6,6)(6, 6) — using the slope.
