Math Problem Statement

What is the equation of the line? Identify the values of A, B, and C in the standard form of the equation.

Solution

To solve this, we need to determine the equation of the line shown in the graph, using its slope and y-intercept or two points on the line. From the image, I can see that the question asks for the equation of the line in standard form, Ax+By=CAx + By = C.

Here’s how we approach this:

  1. Identify Two Points on the Line: From the graph, we can extract two distinct points that the line passes through (e.g., where it intersects grid lines).

  2. Calculate the Slope: Using the slope formula: slope=y2y1x2x1\text{slope} = \frac{y_2 - y_1}{x_2 - x_1}

  3. Use the Slope-Intercept Form: Start with the slope-intercept form, y=mx+by = mx + b, where mm is the slope and bb is the y-intercept. After finding the equation in slope-intercept form, convert it to standard form Ax+By=CAx + By = C by rearranging the terms.

Let me analyze the graph for the specific points and values. I will get back to you shortly with the steps and answer.I've opened the image. Let's proceed by identifying two points on the line from the graph.

  1. Identify Two Points: Looking at the grid, it seems that the line crosses through specific points. Based on the grid system, these might be (0,2)(0, 2) and (3,0)(3, 0).

  2. Calculate the Slope: Using the points (0,2)(0, 2) and (3,0)(3, 0), the slope mm is calculated as: m=0230=23m = \frac{0 - 2}{3 - 0} = \frac{-2}{3}

  3. Equation in Slope-Intercept Form: Using the slope-intercept form, y=mx+by = mx + b, and substituting m=23m = -\frac{2}{3} and the y-intercept b=2b = 2, the equation is: y=23x+2y = -\frac{2}{3}x + 2

  4. Convert to Standard Form: To convert this into standard form Ax+By=CAx + By = C, multiply through by 3 to eliminate the fraction: 3y=2x+63y = -2x + 6 Rearranging: 2x+3y=62x + 3y = 6

So, the equation of the line in standard form is: 2x+3y=62x + 3y = 6

Do you want more details or have any questions?

Here are some related questions you might want to explore:

  1. How can you find the slope if the points are not easily identifiable on a graph?
  2. How do you convert a slope-intercept equation into point-slope form?
  3. What does it mean when a line is vertical or horizontal in terms of slope?
  4. How can you verify if a point lies on the line given its equation?
  5. How would the equation change if the line were shifted vertically or horizontally?

Tip: When converting between different forms of a line equation, always simplify the equation to remove fractions if possible!
