Math Problem Statement

Help me with the first step of this : Write an equation of the line that passes through the given points in​ slope-intercept form. ​(-3​,5​), ​(6​,2​)

Solution

To write the equation of the line in slope-intercept form (y=mx+by = mx + b), we need two key elements: the slope (mm) and the y-intercept (bb).

Step 1: Find the slope (mm) using the slope formula:

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

Given points: (3,5)(-3, 5) and (6,2)(6, 2) m=256(3)=36+3=39=13m = \frac{2 - 5}{6 - (-3)} = \frac{-3}{6 + 3} = \frac{-3}{9} = -\frac{1}{3}

Thus, the slope is m=13m = -\frac{1}{3}.

Do you want me to continue to find the y-intercept and write the final equation?


Here are 5 related questions you might find helpful:

  1. What does the slope represent in the context of a graph?
  2. How can you verify if a given point lies on a line with a specific equation?
  3. What changes to the equation when the slope is zero?
  4. How does the slope-intercept form differ from the point-slope form?
  5. What happens if two points have the same xx-coordinate?

Tip: Always double-check your slope calculation to ensure it matches the relationship between the two points.
