Graph of the Function y = -1/2x + 4

To graph the function y = -1/2x + 4, we can use the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept.

In this case, the slope is -1/2 and the y-intercept is 4. The slope tells us that for every 2 units we move to the right on the x-axis, we move 1 unit down on the y-axis. The y-intercept tells us that the graph intersects the y-axis at the point (0, 4).

To plot the graph, we can choose a few x-values, calculate the corresponding y-values using the equation y = -1/2x + 4, and then plot the points on a coordinate plane.

Let's choose three x-values: -2, 0, and 2.

When x = -2: y = -1/2(-2) + 4 y = 1 + 4 y = 5

So the first point is (-2, 5).

When x = 0: y = -1/2(0) + 4 y = 0 + 4 y = 4

So the second point is (0, 4).

When x = 2: y = -1/2(2) + 4 y = -1 + 4 y = 3

So the third point is (2, 3).

Now we can plot these points on a graph and draw a line through them to represent the function y = -1/2x + 4.


Please note that the graph is a straight line with a negative slope, passing through the point (0, 4). The line extends infinitely in both directions.
