Can someone please answer both these two Algebra questions asap thanks.
1 answer:
Answer:
see explanation
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
(7)
Here m = - 3 and (a, b) = (5, 1), thus
y - 1 = - 3(x - 5) ← equation of line
(8)
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = A(- 2, 1) and (x₂, y₂ ) = B(- 1, 3)
m = = 2
Using any of the 2 points as (a, b)
Using m = 2 and (a, b) = (- 2, 1), then
y - 1 = 2(x - (- 2)), that is
y - 1 = 2(x + 2) ← equation of line

ANSWER
The multiplication, CA is defined, and its dimension is 3×2
EXPLANATION
Matrix A is a 2x3 matrix.
Matrix C is a 3×2 matrix.
The product of the two matrices , CA, is defined if and only if the inner product of their dimension are the same.
The inner products are the same.
Hence the matrix multiplication, CA is defined and its dimension is the outer products.
