Math Problem Statement

Y=2x-3

Solution

The equation Y=2x3Y = 2x - 3 represents a linear function in the slope-intercept form, which is y=mx+by = mx + b, where:

  • m=2m = 2 is the slope of the line, indicating that for every unit increase in xx, yy increases by 2 units.
  • b=3b = -3 is the y-intercept, meaning the line crosses the y-axis at y=3y = -3.

Analysis:

  1. Slope: The slope 22 tells us the line rises 2 units for every 1 unit it moves to the right.
  2. Y-intercept: The line crosses the y-axis at the point (0,3)(0, -3).
  3. X-intercept: To find the x-intercept, set Y=0Y = 0 and solve for xx: 0=2x3    x=32=1.50 = 2x - 3 \implies x = \frac{3}{2} = 1.5 So, the x-intercept is at (1.5,0)(1.5, 0).

Graphing:

  • The line passes through the points (0,3)(0, -3) and (1.5,0)(1.5, 0).
  • It has a positive slope, indicating it slants upward from left to right.
