\[
y=-\frac{1}{4} x+4
\]
Use the graphing tool to graph the line. Use the slope and $y$-intercept when drawing the line
Solution
Solution Steps
Step 1: Identify the slope and y-intercept
The given equation is y=−41x+4. This is in the slope-intercept form y=mx+b, where m is the slope and b is the y-intercept. Here, the slope m is −41 and the y-intercept b is 4.
Step 2: Plot the y-intercept
The y-intercept is the point where the line crosses the y-axis. For the given equation, the y-intercept is 4. Plot the point (0,4) on the graph.
Step 3: Use the slope to find another point
The slope −41 means that for every 4 units you move to the right (positive direction on the x-axis), you move 1 unit down (negative direction on the y-axis). Starting from the y-intercept (0,4), move 4 units to the right to (4,4) and then 1 unit down to (4,3). Plot the point (4,3).
Final Answer
Plot the points (0,4) and (4,3) on the graph and draw a line through these points to represent the equation y=−41x+4.
