Reading a Cartesian plane
Coordinates (x, y)
Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (4, 1)

Point (0, 3)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m=\frac{3-1}{0-4}$
[Fraction] Subtract: $\displaystyle m=\frac{2}{-4}$
[Fraction] Simplify: $\displaystyle m=\frac{-1}{2}$

Change the fraction 3/4 to a percent.

Levart [38]

There is 100% in 1 since this is three parts of 1 we will have to divide 100 by 4 then multiply it by 3.
After you do all the math you will get 0.75.
You can convert this to a percent by just removing the point and the zero and adding a percent at the end.
The answer is going to be 75%

f a football player passes a football from 4 feet off the ground with an initial velocity of 36 feet per second, how long will i

saveliy_v [14]

When it hits the ground h = 0 so we have

-16t^2 + 36t + 4 = 0

t = 2.36 seconds to nearest hundredth.
