Ray BD bisects ∠ABC so that m∠ABD = 5y – 3 and m∠CBD = 2y +12.
Find the value of y.
bisect" means to cut into equal parts.
Thus: 5y – 3 = 2y +12
#2 , let the endpoint be (x,y)
for the x:
(4+x)/2 = 2
4+x = 4
x = 0
for the y:
---- your turn
#3, just use your "distance between 2 points" formula

The formula to find the area of a parallelogram is
area= base x height
area= 11.1 x 7.5
area= 83.25
X can be any number in the graph as long as it is on the x-axis therefore you can put x as -1,0 and 1. Then you would need to replace the ‘x’ in the equation so it would look like y=-2*1+3. You replace ‘x’ with every number you put in the x boxes. Then just solve the equations
y=-2*1+3
Y=-2*0+3
Y=-2*-1+3
They would give you the y axis coordinates so then you just put them together for the middle column.
Answer
y=-2*1+3=1
Y=-2*0+3=3
Y=-2*-1+3=5
Coordinates are (1,3) (0,3) (-1,5)
