Question

he equation y = 8.1x models the relationship between the number of hours Alexander works, x, and the dollar amount he earns, y. Which is the graph of the equation y = 8.1x?

A coordinate grid with a curved line starting at (1, 8) curving down and to the right passing through (2, 4), (4, 2), and (7, 1)

A coordinate grid with a straight line starting at (0, 0) and (1, 8).

A coordinate grid with a straight line starting at (0, 2) passing through (2, 4) and (6, 8).

Answer 1

The graph of the equation is a coordinate grid with a straight line starting at (0, 0) and (1, 8)

Graph of linear equations

From the question, we are to determine the graph of the given equation

The given equation is

y = 8.1x

This is a linear equation since it is of the form

y = mx + b

Where m is the slope

and b is the y-intercept

By comparison,

b = 0

That is, the y-intercept is 0

The graph of the equation is shown below.

From the graph, we can observe that,

We have a coordinate grid with a straight line passing through the point (0, 0) and (1, 8)

Hence,  the graph of the equation is a coordinate grid with a straight line starting at (0, 0) and (1, 8)
