Choose the system of equations that matches the following graph: will insert pic below a) x − 4y = −4 3x + 4y = 36 b) x + 4y = −4 3x − 4y = 36 c) x + 4y = −4 3x + 4y = 36 d) x − 4y = −4 3x − 4y = 36

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

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
