Math Problem Statement

Graph y - 1 = 3(x - 2).

Solution

Let's analyze the equation provided in the image and break down the steps for graphing it.

Equation:

y1=3(x2)y - 1 = 3(x - 2)

Step-by-Step Solution:

  1. Simplify the equation: y1=3(x2)y - 1 = 3(x - 2) Distribute the 3 on the right-hand side: y1=3x6y - 1 = 3x - 6 Add 1 to both sides: y=3x5y = 3x - 5 This is now in slope-intercept form y=mx+by = mx + b, where m=3m = 3 (the slope) and b=5b = -5 (the y-intercept).

  2. Plot the y-intercept: The y-intercept is the point where the line crosses the y-axis. Since b=5b = -5, the line crosses the y-axis at (0,5)(0, -5). This is one point on the line.

  3. Use the slope to find another point: The slope m=3m = 3 means the line rises 3 units for every 1 unit it moves to the right. Starting from the y-intercept (0,5)(0, -5):

    • Move 1 unit to the right (x increases by 1).
    • Move 3 units up (y increases by 3).

    This gives us the point (1,2)(1, -2).

  4. Draw the line: Now that we have two points: (0,5)(0, -5) and (1,2)(1, -2), plot these points and draw a straight line through them.

The line you draw will be the graph of the equation y=3x5y = 3x - 5.
