Here 1 grids crossing means increasing or decreasing by 1 grid. Here we are seeing the line crosses 1 grid above 0. So its positive 1. From here we find the y intercept is +1. Line crosses at coordinate ( 0 , 1 )
The y-intercept of a line is the point of a line that intersects the y-axis. When we look at the line, we can tell that the line is intersecting at (0,1) on the y-axis. When we compare (0,1) to (x,y), we can tell that the intersecting x-coordinate is 0 and the intersecting y-coordinate is 1.
<u>Hence,</u><u> 1</u><u> is the </u><u>y-intercept.</u>
