Question

A linear function is expressed by a graph of a line that

crosses both axes at the origin. An equation is written in
siope-intercept form to express the same function as
shown in the graph From just this information what
statements can be made?
Choose the true statements
The slope of the equation must be positive.
The y-intercept of the equation is zero.
It is possible that the ine on the graph is horizontal
The slope of the equation must be negative

Answer 1

The y-intercept of the equation is zero.

It is possible that the ine on the graph is horizontal

Explanation:

The only thing we know for sure is that the function goes through the point (0,0). The line y = 0 passes through (0,0), so it is possible that the line on the graph is horizontal. Since x = 0 where y = 0, the y-intercept is also 0. However, we have no way of knowing for sure what the slope of the equation is.

Answer 2

The y-intercept of the equation is zero. It is possible that the line on the graph is horizontal.
