Answer:
Slope: 1/2
y-intercept: (0, 4.5)
Slope Intercept = y = mx + b
Slope Intercept = y = 1/2x + 4.5
Explanation:
The slope is 1/2 based on our rule, "Rise over Run" Based on the two points listed on the graph, we can say that we "rise" once and "run" twice. This makes our slope 1/2.
The y-intercept is where the line crosses the y-axis. If use our slope, we can determine that if we "rise" half of our slope in the opposite direction (0.5) and run half of our run in the opposite direction (1) we will intersect at (0, 4.5).
With this information, we can construct our slope-intercept equation:
The slope-intercept formula is as follows: y = mx + b
m is our slope, and b is out y-intercept.
y = 1/2x + 4.5
