13. Write the slope-intercept form of the line described in the following: Parallel to y = 9x - 4 and passing through (1.4)

y-4 = 9(x-1)

Step-by-step explanation:

The formula for slope intercept form is the following:

y-y1 = m(x-x1)

The point given in the problem gives you the values for x1 and y1.

x1=1, y1=4

So far we have y-4 = m(x-1).

We also get m, or slope, from the equation given in the problem. Lines that are parallel have the same slope, so m = 9 (slope indicated in initial equation).

So, the final answer is y-4 = 9(x-1).

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
