Can someone tell me the slope ?

slope = 4

Step-by-step explanation:

We can find the slope of a line when knowing 2 points by using the slope formula, . and represent the x and y values of the first point, respectively. and represent the x and y values of the second point, respectively.

The two points we have are (2,8) and (0,0). So, in this case, = 2, = 8, = 0, and = 0. Let's substitute those values into the formula and solve to get the slope:

So, the slope is 4.

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
