Firstly, we will draw figure
now, we will draw a altitude from B to DC that divides trapezium into rectangle and right triangle
because of opposite sides of rectangle ABMD are congruent
so,
DM=AB=9
CM=CD-DM
CM=18-9
CM=9
now, we can find BM by using Pythagoras theorem
now, we can plug values
we get
now, we can find area of trapezium
now, we can plug values
and we get
so, area of of the trapezoid is ..........Answer
Equation:
y - 10 = -5x
Solve:
(y - 10) + 10 = (-5x) + 10
y = -5x + 10
Remember the formula (Slope Intercept Form):
y = mx + b
m = Slope (Rise/Run)
b = Y-intercept
So your graph would look something like the attached image:
