Answer:OK Lets get one thing straight Not all 2 × 2 matrices have an inverse matrix. If the determinant of the matrix is zero, then it will not have an inverse; the matrix is then said to be singular. Only non-singular matrices have inverses.To find the inverse of a 2x2 matrix: swap the positions of a and d, put negatives in front of b and c, and divide everything by the determinant (ad-bc).
The slope of the line is It can be found from any two points that fall on a line by using the formula 2 is x or y from the second point and 1 is x or y from the first point
For example in that problem the first point is -2,0 and the second one is 0,3
