The height of the ball 2 seconds after being thrown is 20.8m
In order to get the required quadratic function, we need to write the given information as coordinate.
- If the time the ball was initially thrown in the air, it was 7. 5 meters off the ground, this is written in a coordinate form as (0, 7.5)
- If after 1. 25 seconds, the ball was at its maximum height of 15.3125 meters in a coordinate form as (1.25, 15.3125)
Get the slope of the equation;
Get the y-intercept "b"
Recall that y = mx + b
Get the required equation:
Next is to get the height of the ball 2 seconds after being thrown
Hence the height of the ball 2 seconds after being thrown is 20.8m

The slope of the line passing through the points A(a, b), and B(c, d), is given by
thus, the slope of the line through <span>points (p, a) and (p, –a) is
</span>
When applying the slope formula results in division by zero, this means that the line is a vertical line.
This could have also been noticed directly, since the line contains 2 points with the same x-coordinate.
The equation of this line is x=p, since the x-coordinate is always p, no matter what y is.
If p=0, then the equation of the line is x=0, which is the y-axis itself. In this case, the y-intercept is the whole y-axis.
Answer: The whole y-axis.
