Math Problem Statement
I need to graph the following features Y-intercept: 1 and slope=-2/3
Solution
To graph a line with the given features, y-intercept = 1 and slope = -2/3, follow these steps:
Step-by-Step Instructions:
-
Start at the y-intercept: The y-intercept is the point where the line crosses the y-axis. For this line, the point is .
-
Use the slope to find another point: The slope is . This means that for every 3 units you move to the right, the line goes down 2 units.
- From , move 3 units to the right (x = 3), and then 2 units down (y = -1). This gives another point: .
-
Plot these points: Plot and on the graph.
-
Draw the line: Use a ruler to draw a straight line through the points.
Equation of the Line:
The slope-intercept form of a line is: Where:
- is the slope (),
- is the y-intercept (1).
Thus, the equation is:
