Ireally need with this!

part a: list the equations of three lines whose slope is -3.

part b: list the equations of three lines whose y-intercept is 5.

part c: state the equation of the only line with a slope of -3 and a y-intercept of 5. explain why there is only one line that can be formed with this slope and y-intercept.

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

a) 7x=7

step-by-step explanation:

160 cm

step-by-step explanation:

you have to add all the sides together
