Finding the y-intercept, step by step
The y-intercept is where a line crosses the y-axis.
The question
the y-intercept of 5x + y = 5
5x + y = 5x = 0
y = 5
y = 5
- The y-intercept is where the line crosses the y-axis, and there x = 0. Put x = 0 into 5x + y = 5.
- The x-term disappears, leaving y = 5.
- So the y-intercept is 5.
How it works.
- 01
The y-intercept is where the line crosses the y-axis, and there x = 0. Put x = 0 into 5x + y = 5.
- 02
The x-term disappears, leaving y = 5.
- 03
So the y-intercept is 5.
