Linear Equations Find the equation for a graph in the form y=mx+b when you are given two points on the graph. Directions: Enter the points in the form x,y with no spaces, for example, 3,4 or -2.3,5.72 The large text window will show the calculations steps for finding the slope from the two points and then substituting the x,y coordinates to find the value of the y-intercept, b (Repeating decimals, etc. are truncated in the sample problems to make them easier to read)	Find the equation from two points on a grid:
	Enter Point 1 (x₁,y₁) Enter Point 2 (x₂,y₂)

	slope (m) =
	The equation is:

Solving Polynomials by Kramer's Rule

explanation:

Kramer's rule

for:
ax + by = c
dx + ey = f

the following can be applied:

x = (c * e - b * f ) / (a * e - b * d)
y = (a * f - e * d) / (a * e - b * d)

This is known as Kramer's Rule.
