Write the equation for the line

Write the equation for the line

Solution

From the image, I can see a line passing through two points on the coordinate plane. To write the equation of the line, we need the slope mm and the y-intercept bb of the line.

Step 1: Identify Two Points on the Line

Looking at the graph:

  • One point appears to be (6,3)(-6, 3)
  • Another point is at (0,1)(0, 1), which is the y-intercept.

Step 2: Calculate the Slope

The formula for slope mm is:

m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}

Using points (6,3)(-6, 3) and (0,1)(0, 1):

m=130(6)=26=13m = \frac{1 - 3}{0 - (-6)} = \frac{-2}{6} = -\frac{1}{3}

Step 3: Write the Equation

Since we already know that the y-intercept b=1b = 1 (from the point (0,1)(0, 1)), the equation of the line in slope-intercept form y=mx+by = mx + b is:

y=13x+1y = -\frac{1}{3}x + 1

This is the equation of the line.

Here are some related questions to explore further:

  1. What is the significance of the slope in the equation of a line?
  2. How do you convert a line equation from slope-intercept form to standard form?
  3. What would the line look like if the slope were positive?
  4. How do we interpret the y-intercept in the context of real-world problems?
  5. How can we determine the x-intercept from this equation?

Tip: Always plot at least two points when graphing a line to ensure accuracy!
