Math Problem Statement

Write the equation of a line in slope-intercept form when y-intercept is (0, -2) and slope is -7/6.

Solution

To write the equation of a line in slope-intercept form y=mx+by = mx + b, you need the slope (mm) and the y-intercept (bb).

From the given problem:

  • The slope m=76m = -\frac{7}{6}
  • The y-intercept b=2b = -2

Substitute these values into the slope-intercept form:

y=76x2y = -\frac{7}{6}x - 2

Thus, the equation is:

y=76x2y = -\frac{7}{6}x - 2

Here are 5 related questions for further exploration:

  1. How do you derive the slope-intercept form equation if two points are given instead of the slope and y-intercept?
  2. What is the meaning of the slope in a real-world context?
  3. How can you rewrite a slope-intercept equation into standard form?
  4. What happens to the line if the slope becomes positive but the y-intercept remains the same?
  5. How do you graph a line using only its slope-intercept form?

Tip: When graphing a line from the slope-intercept form, the y-intercept provides a starting point, and the slope indicates how the line "rises" or "runs" from that point.
