<h3>Linear equation</h3>Linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Let y represent the number of balloons for x animals.
Amira uses 4 balloons for each animal.
For Mandisa, using the table using (20, 225) and (60, 25):
Therefore Mandisa uses 5 balloons for each animal, this means that Mandisa uses more.

You can use a tangent:
We have opposite = 17 and adjacent = x.
substitute:
cross multiply
multiply both sides by √3
divide both sides by 3
Use the Pythagorean theorem:

Other method.
triangle.
The sides are in the ratio
Therefore
The first graph.
The equation is x - 1
