Math Problem Statement

what is the Y intercepts of 3X plus 8Y equals 48

Solution

To find the y-intercept of the equation 3X+8Y=483X + 8Y = 48, follow these steps:

  1. The y-intercept occurs when X=0X = 0. So, substitute X=0X = 0 into the equation:

3(0)+8Y=483(0) + 8Y = 48

  1. Simplifying the equation:

8Y=488Y = 48

  1. Solve for YY:

Y=488=6Y = \frac{48}{8} = 6

Therefore, the y-intercept is Y=6Y = 6, or as a point, it is (0,6)(0, 6).

  3. Can you rewrite the equation 3X+8Y=483X + 8Y = 48 in slope-intercept form?
  4. What happens to the y-intercept if the equation changes to 3X+8Y=603X + 8Y = 60?
  5. How would you graph the line 3X+8Y=483X + 8Y = 48?

Tip: The y-intercept is always the point where the graph crosses the y-axis (when X=0X = 0).
