What is the y-intercept of this line?

Answer 1

The y-intercept is 1

Explanation:

If you look at this graph, we have a linear line (no curves). Therefore we can set both points on the graph, then adjust the slope. In this case, the y-intercept is 1, and we have a slope of -0.25 meaning that for every 2 right squares, we decrease by half a square on our y-axis.

Hope this helps :)
