Answer:

y = 1.5x

Step-by-step explanation:

We are to find the equation of the straight line

Using the coordinate (0, 0) and (200, 300)

Slope m = 300-0/200-0

m = 300/200

m = 1.5

Since the line pass through the origin, the y intercept is 0

Substitute m = 1.5 and b =0 into y = mx+b

y = 1.5x + 0

y = 1.5x

This gives the required equation

Answer:

Step-by-step explanation:

A 5x8 matrix $A$ represents a linear transformation between the vector space $\mathbb{R}^8$ and $\mathbb{R}^5$ . Remeber that the columns of $A$ generate the image of the linear transformation, which is a vector subspace of $\mathbb{R}^5$ . Therefore, $\dim \text{Col}A \leq 5$ , which is the dimension of the the total space.
