Answer: y=-3/10+1/2
Here is a model equation: y=mx+b
Y-intercept: Unit where the line crosses on the y-axis. This is b in the equation. In this case it is 1/2.
Slope: This is the m in the equation. You do this by finding two points, seeing how many unit up and down to find it over how many unit left and right. Using the two dots on the graph, this would be -3/10, because the graph is also negative.
