Math Problem Statement
y=mx+b m=-2 b=2 Solve it and graph it
Solution
The equation you provided is in the slope-intercept form , where is the slope, and is the y-intercept.
Given:
The equation becomes:
Steps to solve and graph:
-
Identify key points:
-
The y-intercept occurs when , so: Thus, one point on the graph is .
-
The slope means that for every 1 unit increase in , decreases by 2 units.
-
-
Find another point: Choose another value of , say : So another point is .
-
Plot these points: Plot and on a graph, and draw a straight line through them, which represents the equation .
I can also graph this for you if you'd like to see the visual. Would you like a graph?
Here are some questions to think about:
- How do changes in slope affect the steepness of the graph?
- What would happen if the y-intercept was negative?
- What is the significance of the slope in real-life applications?
- How does a vertical shift affect the equation of a line?
- Can you find the x-intercept of this line?
Tip: The slope tells you how fast the line rises or falls, and the y-intercept tells you where it crosses the y-axis.
