The y-intercept occurs when we cross the y-axis (at the point that x is 0)
Looking at our table, when x = 0, y = 4.
So, our y-intercept is 4.
Slope is (the change in y)/(the change in x)
Let's use the first two points in our table. (-3, 10) and (0,4)
- m = (y2 - y1) / (x2 - x1)
- m = (4 - 10) / (0 - (-3))
- m = (-6) / (3)
- m = -2
So, our slope is -2. Assuming the data in your table is linear, the slope should be the same regardless of which two points you pick.
