Math Problem Statement

Graph this line using the slope and y-intercept: y = (5/7)x - 10

Solution

The equation of the line given is y=57x10y = \frac{5}{7}x - 10, which is in slope-intercept form, y=mx+by = mx + b, where:

  • The slope m=57m = \frac{5}{7}.
  • The y-intercept b=10b = -10.

To graph this line:

  1. Start by plotting the y-intercept at (0,10)(0, -10) on the graph. This is where the line crosses the y-axis.
  2. Use the slope to determine another point. The slope 57\frac{5}{7} means "rise over run" (i.e., move 5 units up for every 7 units you move to the right). So, from the y-intercept (0,10)(0, -10), move 7 units to the right and 5 units up to get to the point (7,5)(7, -5).
  3. Plot this second point (7,5)(7, -5), and draw a straight line through the two points.

These steps will give you the line that represents the equation.

Tip: Remember, the slope tells you how steep the line is. If the slope is positive, the line will rise from left to right; if the slope is negative, the line will fall from left to right.
