Math Problem Statement

What are the coordinates of the y-intercept of the line y = 6x + 14?

Solution

The equation of the line is given as y=6x+14y = 6x + 14.

This is in the form of the slope-intercept form of a line, which is:

y=mx+by = mx + b

where:

  • mm is the slope,
  • bb is the y-intercept.

In this case, b=14b = 14, meaning the y-intercept of the line is at y=14y = 14.

To find the coordinates of the y-intercept, set x=0x = 0 (since the y-intercept occurs when the line crosses the y-axis, where x=0x = 0):

y=6(0)+14=14y = 6(0) + 14 = 14

Thus, the coordinates of the y-intercept are (0,14)(0, 14).

Here are 5 related questions you might explore:

  1. What is the slope of the line and what does it represent?
  2. How would you find the x-intercept of the line?
  3. What happens to the y-intercept if the equation changes to y=6x5y = 6x - 5?
  4. How would you graph this line using its slope and y-intercept?
  5. What would the equation of a line parallel to this one look like?

Tip: The y-intercept is always where x=0x = 0, so you can quickly find it by plugging in x=0x = 0 in the equation of the line.
