Which graph represents a proportional relationship? On a coordinate plane, a line crosses the y-axis at (0, 2). On a coordinate plane, a line crosses the y-axis at (0, 2). On a coordinate plane, a curved line curves at (0, 0). On a coordinate plane, a line crosses the y-axis at (0, 0).

On a coordinate plane, a line crosses the y-axis at (0,0)

Step-by-step explanation:

A proportional relationship has the form:

y = k*x

where k is the constant of proportionality.

only from looking at this we can conclude:

This is a linear equation.

The slope is k.

The y-intercept is equal to zero.

For example, if we have x = 0 then:

y = k*0 = 0

then this line passes through the point (0,0)

then the correct option is:

"On a coordinate plane, a line crosses the y-axis at (0,0)"
