QuestionGraph the line with the equation .
Studdy Solution
STEP 1
What is this asking?
Draw the line represented by the equation on a coordinate plane.
Watch out!
Make sure to correctly interpret the equation and plot the points accurately.
Don't mix up the and values!
STEP 2
1. Find the y-intercept.
2. Find the x-intercept.
3. Plot the line.
STEP 3
To **find the y-intercept**, we set in our equation because the y-intercept is where the line crosses the y-axis, and the x-coordinate is always **zero** on the y-axis.
STEP 4
Substituting into , we get .
STEP 5
So, .
This means our **y-intercept** is at the point .
STEP 6
To **find the x-intercept**, we set because the x-intercept is where the line crosses the x-axis, and the y-coordinate is always **zero** on the x-axis.
STEP 7
Substituting into , we get .
STEP 8
Now, we want to isolate .
We can do this by adding 4 to both sides of the equation: .
STEP 9
This simplifies to , or .
So, our **x-intercept** is at the point .
STEP 10
We have our two points: the **y-intercept** and the **x-intercept** .
Let's plot these points on the graph!
STEP 11
Now, draw a straight line through these two points, extending it in both directions.
This line represents all the points that satisfy the equation .
STEP 12
The line passes through the points and on the coordinate plane.
