In which step did Samuel make an error?
In step 1, he substituted the x values for y and the y values for x.
In step 2, he made an arithmetic error.
In step 3, he substituted the wrong values for m and b.
Samuel did not make an error.

b.an increase in a causes b to decrease

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
