What is the value of y if the line through the two given points is to have the indicated slope (4,y) and (2,6), M=-4?

y= -2

Step-by-step explanation:

y2-y1      6-y =  8

x2-x1       2-4= -2

To solve for y : Your answer has to be 8 then you divide 8/-2 = -4

6-y=8

subtract 6 from both sides   = -y =2

multiply each side by(-1)

to remove the - from Y         (-1)y =(-1)2

                                                   y =-2

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

0 is its x and y coordinate
