Answer 2

Graph of the Function y = 4x + 8

To graph the function y = 4x + 8, 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 (m) is 4, and the y-intercept (b) is 8.

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

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

When x = -2: y = 4(-2) + 8 = -8 + 8 = 0

When x = 0: y = 4(0) + 8 = 0 + 8 = 8

When x = 2: y = 4(2) + 8 = 8 + 8 = 16

Now, we can plot the points (-2, 0), (0, 8), and (2, 16) on a graph.


The graph of the function y = 4x + 8 is a straight line with a slope of 4 and a y-intercept of 8. It passes through the points (-2, 0), (0, 8), and (2, 16).
