Your slope=-2
Which is 2/1 (rise/run)
Your y-int=-1 (which means your graph should touch the -1 on the y-int
So your answer would be A
The answers are as follows:
1-D
2-B
3-C
4-A
a) By Pythagoras theorem , h^2 is = a^2 + b^2 where a is the hypotenuse and a and b are the legs.
=) 15^2 = x^2 + y^2
That is the relation
b) area of triangle = 1/2 x height x base
=) 1/2 * x * y = 30
=) xy = 15cm
