Math Problem Statement

Rewrite and graph the equation y - (-5) = -5/7(x - 14).

Solution

The equation provided is:

y(5)=57(x14)y - (-5) = -\frac{5}{7}(x - 14)

Step-by-Step Simplification

  1. Simplify y(5)y - (-5) to y+5y + 5: y+5=57(x14)y + 5 = -\frac{5}{7}(x - 14)

  2. Expand the right-hand side: y+5=57x+707y + 5 = -\frac{5}{7}x + \frac{70}{7}

    Simplify the constant term 707\frac{70}{7} to 10: y+5=57x+10y + 5 = -\frac{5}{7}x + 10

  3. Subtract 5 from both sides to isolate yy: y=57x+105y = -\frac{5}{7}x + 10 - 5

    Simplify: y=57x+5y = -\frac{5}{7}x + 5

Final Equation

The equation in slope-intercept form is: y=57x+5y = -\frac{5}{7}x + 5

Instructions for Graphing

  1. Slope: The slope is 57-\frac{5}{7}, meaning for every 7 units you move to the right, the line moves 5 units downward.
  2. Y-Intercept: The y-intercept is 55, meaning the line crosses the y-axis at y=5y = 5.

Plotting on the Grid

  1. Mark the y-intercept at (0,5)(0, 5).
  2. From that point, use the slope 57-\frac{5}{7}:
    • Move 7 units to the right and 5 units down to (7,0)(7, 0).
  3. Connect the points to draw the line.
