The graph is a straight line .
Mark 2 points on the coordinate plane
When x = 0 , 2y = 24 so y = 12 so it
is the point (0, 12)
The other point is
When y = 0 , 8x = 24 so x = 3
The point is (3,0)
The straight line through these 2 points is your graph.

Answer:

See the attached image.

Explanation:

We can most easily sketch an accurate graph of a linear function by converting it to slope-intercept form:


y = mx + b

In this form, two characteristics are apparent:


  • m — the line's slope

  • b — the y-coordinate of the line's y-intercept

We can rewrite the given equation:


8x + 2y = 24

in slope-intercept form by isolating y with the following steps:

subtracting
8x from both sides


2y = -8x + 24

dividing both sides by
2


y = -4x + 12

Now, comparing this to slope-intercept form, we can identify the following values:

  • m = slope (rise / run) = -4
  • b = y-intercept = 12

See the attached image for the graph of a line with these characteristics.
