the complete question is
Which phrase best describes the graph of a proportional relationship?
A.a straight line passing through the origin
B.a straight line
C.a curve
D.not a straight line
we know that
A relationship between two variables, x, and y, represent a proportional relationship (direct variation) if it can be expressed in the form
the equation is a straight line passing through the origin with slope equal to k
therefore
the answer is the option
A.a straight line passing through the origin

Answer: FIRST OPTION
Step-by-step explanation:
<h3> The missing picture is attached.</h3>By definition, given a Quadratic equation in the form:
Where "a", "b" and "c" are numerical coefficients and "x" is the unknown variable, you caN use the Quadratic Formula to solve it.
The Quadratic Formula is the following:
In this case, the exercise gives you this Quadratic equation:
You can identify that the numerical coefficients are:
Therefore, you can substitute values into the Quadratic formula shown above:
You can identify that the equation that shows the Quadratic formula used correctly to solve the Quadratic equation given in the exercise for "x", is the one shown in the First option.
