Answer:
m = slope = -3/2; b = y-intercept = 1
Explanation:
The graph (the sloping line) intersects the y-intercept at (0, 1). Thus, b = 1.
Starting with your pencil point on (0,1), move it to (2, -2). Notice how x increases by 4 and y decreases by 6.
Thus, the slope of this line is m = rise/run = -6/4, or m = -3/2.
m = slope = -3/2; b = y-intercept = 1
