Answer:
slope = -2
y-intercept = 2
equation: y = -2x + 2
Step-by-step explanation:
The equation of a line is
y = mx + b
We need to find the slope, m, and the y-intercept, b.
The graph crosses the y-axis at y = 2, so the y-intercept, b, equals 2.
Now we have
y = mx + 2
slope = m = rise/run
We see points (1, 0) and (0, 2) on the graph. Starting at (1, 0), we go up 2 units. That is a rise of 2. Then we go 1 unit left. That is a run of -1.
slope = m = rise/run = 2/(-1) = -2
The slope is -2.
The equation is
y = -2x + 2
