Math Problem Statement

y=-2x+7

Solution

The given equation is a linear equation in slope-intercept form:

y=2x+7y = -2x + 7

Here:

  • The slope m=2m = -2, which means the line decreases by 2 units vertically for every 1 unit it moves horizontally to the right.
  • The y-intercept b=7b = 7, meaning the line crosses the y-axis at the point (0,7)(0, 7).

Graphical Interpretation:

  • The line will pass through the point (0,7)(0, 7) and will have a downward slope, meaning it will go down 2 units for every 1 unit it moves to the right.
