Finding the Slope
The slope of the equation is . This means that for every one unit increase in x, y increases by units. This is a positive slope, indicating that the line slopes upward from left to right.
Finding the Y-Intercept
The y-intercept of the equation is 1. This means that when x is equal to zero, y is equal to 1. This is the point where the line intersects the y-axis.
Graphing the Line
To graph the line, we can use the slope and the y-intercept to find two points on the line. We can then draw a line through these two points to represent the equation.
Finding Two Points on the Line
To find two points on the line, we can substitute different values of x into the equation and solve for y. Let's substitute x = 0 and x = 3 into the equation.
Substituting x = 0
When x is equal to zero, the equation becomes:
Simplifying the equation, we get:
Adding 1 to both sides, we get:
So, when x is equal to zero, y is equal to -1. This is the first point on the line.
Substituting x = 3
When x is equal to 3, the equation becomes:
Simplifying the equation, we get:
Adding 1 to both sides, we get:
So, when x is equal to 3, y is equal to 1. This is the second point on the line.
Drawing the Line
Now that we have two points on the line, we can draw a line through these two points to represent the equation. The line will have a slope of and a y-intercept of 1.
