What does the Y-intercept represents in a linear equation?
The Y-intercept represents the point where the line crosses the Y-axis.
100
What is an equation?
An equation is written as two expressions, connected by an equal sign ''=''.
100
The point where the x-axis and y-axis intersect is called the?
Origin point.
200
What does a positive slope indicate in terms of the line's direction?
A positive slope indicates that the line is going upward from left to right.
200
How can you tell if the Y-intercept will be added or subtracted?
If the y-intercept is positive, it will be added.
If the y-intercept in negative, it will be subtracted.
