On your calculator, find the inverse. ... The inverse will always go first, so the equation will look like this: AX= B. A-1AX = A-1B We need to multiply by the inverse to both sides. notice how the inverse is on the left of the everything on each side. ... Convert the above example into a matrix equation. Step 6.

For Problem 1, the data is modeled by the polynomial y = ax + b. We can use matrices to find the values of a and b. 11. Write the general form of a linear equation two times. In one of them, substitute the x- and y values of third point. In the other, substitute the x- and y-values of the fourth point. You will now have a system of equations. 12.
