Question

Which of the equations matches the line shown in the diagram? Responses A y = − x y = − 5 3 x B y = − x − 1y = − 5 3 x − 1 C y = x + 1 y = 5 3 x + 1 D y = x −

Answer 1

The calculated equation that matches the line is y = -x

How to determine the equations matches the line

From the question, we have the following parameters that can be used in our computation:

The graph

We can see that

The line on the graph passes through the origin

This means that the equation can be represented as

y = mx

Where m is the slope

On the graph, we have the point (1, -1)

So, we have

m(1) = -1

Evaluate

m = -1

Recall that

y = mx

So, we have

y = -x

Hence, the equation that matches the line is y = -x

Question

Which of the equations matches the line shown in the diagram? Responses

y = − x

y = − 5/3 x

y = − x − 1

y = − 5/3x − 1

y = x + 1

y = 5/3x + 1
