Math Problem Statement

solve

Find the slope and the y-intercept of the line: y = x + 3

Solution

The equation given in the image is:

y=x+3y = x + 3

This equation is in the slope-intercept form, which is generally written as:

y=mx+by = mx + b

Where:

  • mm is the slope of the line.
  • bb is the y-intercept (the value of yy when x=0x = 0).

From the given equation:

  • The slope (mm) is the coefficient of xx, which is 11.
  • The y-intercept (bb) is 33, as it is the constant term.

Answer:

  • Slope: 1
  • y-intercept: 3

Do you have any questions or need further details?

Follow-up questions:

  1. How do you find the slope if the equation is not in slope-intercept form?
  2. What does a negative slope represent?
  3. How do you graph a line using the slope and y-intercept?
  4. What if the equation has no xx-term? What would be the slope?
  5. How can you convert a standard form equation to slope-intercept form?

Tip: Always look for the coefficient of xx to determine the slope when using the slope-intercept form of a line equation!
