1 answer:

4 0

Hello : let A(2,5) B(-1,8)
the slope is : (YB - YA)/(XB -XA)= (8-5)/(-1-2)=3/-3 = -1
the equation in point-slope form is : y-5 = -(x-2)

Answer:

y=1/2x+8

Step-by-step explanation:

y=mx+c

gradient will stay the same = 1/2

y=1/2x+c

5= 1/2(-6)+c

5=-3+c

+3 on both sides

8=c

y=1/2x+8 will be parallel to y=1/2x-7

Answer:

3y+4+2y+16=180 sum of two opposite angle of the cyclic quadrilateral is 180

5y=180-20

y=160/5=32

again

2x+58=180sum of two opposite angle of the cyclic quadrilateral is 180

2x=180-58

x=122/2=61

Check the picture below.

notice, when dividing we have to put the dividend in descending order, now, the cubic, square and single terms are there, but they have a coefficient of 0, as you see in the picture in green, so we add those properly.
