1. Problem Description

The problem asks us to graph the function f(x)=34x+5f(x) = \frac{3}{4}x + 5. This is a linear function in the form y=mx+by = mx + b, where mm is the slope and bb is the y-intercept.

2. Solution Steps

First, we identify the slope and y-intercept of the function. The given function is f(x)=34x+5f(x) = \frac{3}{4}x + 5. Comparing this with the slope-intercept form y=mx+by = mx + b, we have:
m=34m = \frac{3}{4} (slope)
b=5b = 5 (y-intercept)
The y-intercept is the point where the line crosses the y-axis, which is (0,5)(0, 5). We can use the slope to find another point on the line. The slope 34\frac{3}{4} means that for every 4 units we move to the right along the x-axis, we move 3 units up along the y-axis. Starting from the y-intercept (0,5)(0, 5), if we move 4 units to the right (i.e., x=4x=4), the y-value will increase by 3, so we have:
y=34(4)+5=3+5=8y = \frac{3}{4}(4) + 5 = 3 + 5 = 8
So, the point (4,8)(4, 8) is also on the line. We can graph the line using the points (0,5)(0, 5) and (4,8)(4, 8).

3. Final Answer

The graph of the function f(x)=34x+5f(x) = \frac{3}{4}x + 5 is a straight line passing through the points (0,5)(0, 5) and (4,8)(4, 8).
