Answer:
m= 1/2, b=-1
Step-by-step explanation:
Slope is Rise over Run, create a "slope triangle" by using the grid lines of the graph and the graphed line. From the point (0, -1), you can vertically run a line one unit up, and then horizontally run two units to the right (both positive directions). Therefore Rise = 1 and Run = 2.
The point (0, -1) identifies the y-intercept, when x = 0, the coordinate of "y" is the y-intercept.
The slope-intercept form of this graph is y = 1/2x - 1
