Answer:
see attached
Step-by-step explanation:
Your calculator, spreadsheet, or any number of apps or web sites can compute a matrix product for you. The requirement for the product to exist is that the number of columns in the left matrix match the number of rows in the right matrix.
The product term at location (row, column) = (j, k) in the product is the dot-product of row j in the left matrix with column k in the right matrix. For example, in this matrix product, term (1,2) in the product is the dot-product ...
[1, -2]·[4, -7] = (1)(4) +(-2)(-7) = 4 +14 = 18 . . . product term (1, 2)

Answer: B -8/7x+11/7
Step-by-step explanation:
First find the slope using teh formule which is teh formula for slope in this case the slope would be (-8/7) then pick a pair of points in this case we will use (4,-3) plug in the slope and the coordinate pair into the intercept formula (y=mx+b) so it would look like -3=-8/7(4)+b then solve for b so the answer be 8/7x+11/7
