Math Problem Statement

Given y = (3/4)x + 1, a table of values, and ordered pairs. Choose the correct graph for the ordered pairs on the coordinate plane with the straight-line solution through the plotted points and whether it is proportional or non-proportional.

Solution

I see you've uploaded an image with mathematical content. Let me analyze it and provide you with the necessary solution or explanation.

Give me a moment to examine the details!I've analyzed the image, and it contains a table of values for a linear function y=34x+1y = \frac{3}{4}x + 1. The task asks for identifying the graph corresponding to the function and determining whether it represents a proportional or non-proportional relationship.

Here are the steps to analyze it:

  1. Table of Values:

    • The table shows corresponding values of xx and yy for different xx-values. For instance, for x=4x = -4, y=2y = -2, and for x=0x = 0, y=1y = 1. These values are consistent with the equation y=34x+1y = \frac{3}{4}x + 1.
  2. Graph Interpretation:

    • The graph of a linear equation like this one represents a straight line. The slope is 34\frac{3}{4}, which is positive, indicating an increasing line.
    • The yy-intercept is 1, which means the line crosses the yy-axis at y=1y = 1.
  3. Proportional vs. Non-Proportional:

    • A proportional relationship would pass through the origin (0,0). Since the yy-intercept here is 1 (not 0), the relationship is non-proportional.

Would you like further details or clarification on this? I can also help with more questions related to linear equations!


Follow-up Questions:

  1. How do you identify the slope and y-intercept from the equation of a line?
  2. What is the difference between proportional and non-proportional relationships in linear functions?
  3. How can you graph a linear equation using a table of values?
  4. How would the graph change if the slope was negative instead of positive?
  5. How do you convert the equation y=34x+1y = \frac{3}{4}x + 1 into slope-intercept form?

Tip: When identifying proportional relationships, always check if the line passes through the origin (0, 0). If it does, the relationship is proportional!
