You can use point-slope form to find the equation of a line if you know any two points the line passes through and find the line's slope. for example, let's find the equation of the line passing through points (−1, 1) and (1, 2).

y=1/2x+1/5

Step-by-step explanation:

2-1=m(1+1)

1=m(2)

1/2=m

Plug it into your y=mx+b

y=1/2x+b

Find b by plugging one of your ordered pairs in

2=1/2(1)+b

2=1/2+b

1.5=b

Plug it into your original expression

y=1/2x+1.5

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

11

step-by-step explanation:

32.50-7.50=25

225/25=11
