A ball was tossed up into the air. The height of the ball as a function of the time the ball is in the air in seconds can be mod
1 answer:
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

Answer: I'm not going to give out the answers but I'm happy to explain it and help you out if you're still confused. I'm a geometry honors student rn btw just so you know my credentials.
Step-by-step explanation:
To find slope and write it in slope-intercept form you first need to know the equation and what different variables represent.
y = mx + b is the equation for slope-intercept. You need to find what m and b are to right a slope-intercept equation. for example the first problem's answer is y = x + 1
m is slope which is the angle that the line is at. To find slope or m, you need to choose a point on the graph. Then, count the amount of spaces vertically and horizontally until the next point on the graph. When I say point, I'm referring to a place on the graph where the line cross perfectly over the intersection of two lines on the graph. Slope is always 'rise over run' meaning it is a fraction containing the amount up or down, over the amount left or right. For example, the first problem (the one on the top left) the slope is .
b is the y-intercept. The y intercept where the line crosses the y-axis which is that bold line going up and down in the middle. For example in number one, the y-intercept is 1 because it is one unit up from the origin. (the origin is 0,0, or the very middle of the graph).
Hope this helps! :)
