Math Problem Statement
Graph this line: y+4=– 5(x–5)
Solution
To graph the equation , we first need to rewrite it in slope-intercept form, which is , where is the slope and is the y-intercept.
Step 1: Simplify the equation
We start with:
First, distribute the on the right-hand side:
Next, subtract 4 from both sides to isolate :
Now, we have the equation in slope-intercept form:
Step 2: Graph the line
- Slope : This means for every 1 unit increase in , decreases by 5 units.
- Y-intercept : The line crosses the y-axis at .
Graphing Steps:
- Start at the y-intercept (0, 21) on the graph.
- From there, use the slope to plot another point. From , move 1 unit to the right (positive ) and 5 units down (negative ) to the point .
- Draw a straight line through the points and .
