Math Problem Statement

Find the slope and y-intercept for each of the following equations: 1. 2x + 3y = 6 2. 3x + y = -2 3. x + 2y = -1 4. 4x - y = 3 5. 3x - 2y = 5 6. x - y = 3 7. 2x - 2y = -1 8. 3x + 4y = -8 9. 2x - y = 0 10. x + y = 2

Solution

Let me extract the equations from the image and compute the slope and y-intercept for each equation.

Steps to Solve:

  1. Rewrite each equation in the slope-intercept form (y=mx+by = mx + b).
  2. Identify the slope (mm) and y-intercept (bb).

Here’s the analysis for each equation:

  1. 2x+3y=62x + 3y = 6
    Rearrange to slope-intercept form:
    3y=2x+6    y=23x+23y = -2x + 6 \implies y = -\frac{2}{3}x + 2
    Slope (mm) = 23-\frac{2}{3}, y-intercept (bb) = 2.

  2. 3x+y=23x + y = -2
    Rearrange:
    y=3x2y = -3x - 2
    Slope (mm) = 3-3, y-intercept (bb) = 2-2.

  3. x+2y=1x + 2y = -1
    Rearrange:
    2y=x1    y=12x122y = -x - 1 \implies y = -\frac{1}{2}x - \frac{1}{2}
    Slope (mm) = 12-\frac{1}{2}, y-intercept (bb) = 12-\frac{1}{2}.

  4. 4xy=34x - y = 3
    Rearrange:
    y=4x+3    y=4x3-y = -4x + 3 \implies y = 4x - 3
    Slope (mm) = 4, y-intercept (bb) = 3-3.

  5. 3x2y=53x - 2y = 5
    Rearrange:
    2y=3x+5    y=32x52-2y = -3x + 5 \implies y = \frac{3}{2}x - \frac{5}{2}
    Slope (mm) = 32\frac{3}{2}, y-intercept (bb) = 52-\frac{5}{2}.

  6. xy=3x - y = 3
    Rearrange:
    y=x+3    y=x3-y = -x + 3 \implies y = x - 3
    Slope (mm) = 1, y-intercept (bb) = 3-3.

  7. 2x2y=12x - 2y = -1
    Rearrange:
    2y=2x1    y=x+12-2y = -2x - 1 \implies y = x + \frac{1}{2}
    Slope (mm) = 1, y-intercept (bb) = 12\frac{1}{2}.

  8. 3x+4y=83x + 4y = -8
    Rearrange:
    4y=3x8    y=34x24y = -3x - 8 \implies y = -\frac{3}{4}x - 2
    Slope (mm) = 34-\frac{3}{4}, y-intercept (bb) = 2-2.

  9. 2xy=02x - y = 0
    Rearrange:
    y=2x    y=2x-y = -2x \implies y = 2x
    Slope (mm) = 2, y-intercept (bb) = 0.

  10. x+y=2x + y = 2
    Rearrange:
    y=x+2y = -x + 2
    Slope (mm) = 1-1, y-intercept (bb) = 2.


Let me know if you'd like detailed steps for any particular equation or need clarifications.

Here are 5 related questions:

  1. How do you determine the slope and y-intercept from a linear equation graphically?
  2. What is the relationship between parallel lines and their slopes?
  3. How do you convert between standard form and slope-intercept form?
  4. What does it mean if two equations have the same slope but different y-intercepts?
  5. How can you verify the slope and y-intercept algebraically?

Tip: Always simplify the equation to the slope-intercept form for easier graphing and interpretation!
