Answer

$y=1/2x-1$

Work Step by Step

To put the equation into slope intercept form, we need to find the y-intercept and the slope of the line. Recall, slope equals rise over run. We see that for every one the line rises, it goes over two, so we know that the slope is 1/2. We see that the line crosses the y-axis at the y-value of -1, so we know that the y-intercept is -1. Thus, we find the equation: $y=1/2x-1$
