What is the shape of a linear function on a coordinate plane.

choices are:

a. circle
b. ellipse
c. vertical
d. horizontal

I chose "D"

I think its c but im not entirely sure

Your question makes no sense to me.

A linear function is a straight line.
Tha't like asking, "What is the shape of a straight line?"

The shape of a linear function on a coordinate plane depends on its slope. A linear function represents a line, so its shape can be either horizontal or vertical.

If a linear function has a slope of 0, it is a horizontal line. This means that the line is parallel to the x-axis and does not change in the y-direction. So, the correct answer is option (d) horizontal.

To determine the slope of a linear function, you can use the formula (change in y) / (change in x) between any two points on the line. If the slope is zero, it is a horizontal line. If the slope is undefined (because the change in x is zero), it represents a vertical line.
