Math Problem Statement

What is the slope of a line represented by the equation y = 5/3 x + 8? Express your answer as a fraction in least terms.

Solution

To find the slope of the line represented by the equation

y=53x+8y = \frac{5}{3}x + 8

we need to identify the coefficient of xx in this slope-intercept form y=mx+by = mx + b, where mm is the slope and bb is the y-intercept.

In this case:

  • The coefficient of xx is 53\frac{5}{3}, which means the slope m=53m = \frac{5}{3}.

So, the slope of the line is:

53\frac{5}{3}

Here are 5 related questions to expand your understanding:

  1. What is the y-intercept of the line in this equation?
  2. How would the slope change if the equation was y=53x+8y = -\frac{5}{3}x + 8?
  3. How can you determine the slope from an equation that is not in slope-intercept form?
  4. What does a positive slope indicate about the direction of the line?
  5. How would the line's equation change if the slope were 35\frac{3}{5} instead?

Tip: In slope-intercept form, the coefficient of xx always represents the slope, making it easy to identify the line's steepness and direction.
