Math Problem Statement

Graph the equation using the​ x- and​ y-intercepts. 8xminus4yequalsnegative 32 Question content area bottom left Part 1 Use the graphing tool to graph the equation. Use the intercepts when drawing the line. If only one intercept​ exists, use it and another point to draw the line.

Solution

To graph the equation 8x4y=328x - 4y = -32 using the x- and y-intercepts, follow these steps:

  1. Find the x-intercept:

    • Set y=0y = 0 in the equation and solve for xx. 8x4(0)=32    8x=32    x=48x - 4(0) = -32 \implies 8x = -32 \implies x = -4 So, the x-intercept is (4,0)(-4, 0).
  2. Find the y-intercept:

    • Set x=0x = 0 in the equation and solve for yy. 8(0)4y=32    4y=32    y=88(0) - 4y = -32 \implies -4y = -32 \implies y = 8 So, the y-intercept is (0,8)(0, 8).
  3. Plot the intercepts:

    • Mark the points (4,0)(-4, 0) and (0,8)(0, 8) on the graph.
  4. Draw the line:

    • Connect the two intercepts with a straight line to graph the equation.

Here’s a step-by-step breakdown of the graph:

  • X-intercept: (4,0)(-4, 0)
  • Y-intercept: (0,8)(0, 8)
  • Equation in slope-intercept form: y=2x+8y = 2x + 8
