Math Problem Statement

help me with the first step to graphing the following equation: f(x)=-3/4x-6

Solution

To graph the equation f(x)=34x6f(x) = -\frac{3}{4}x - 6, the first step is to identify key features of the line. Here's how you start:

  1. Rewrite the equation in slope-intercept form: The equation is already in slope-intercept form, f(x)=mx+bf(x) = mx + b, where:

    • m=34m = -\frac{3}{4} is the slope.
    • b=6b = -6 is the y-intercept.
  2. Plot the y-intercept:

    • The y-intercept (bb) is the point where the line crosses the y-axis. This occurs when x=0x = 0.
    • Plot the point (0,6)(0, -6) on the graph.

Would you like a detailed step-by-step guide for the next steps or a graph of this equation?

Tip:

When working with slopes like 34-\frac{3}{4}, remember it means "down 3 units and right 4 units" to find additional points along the line.
