Answer:
The equation of line is y+2=0
Step-by-step explanation:
The equation of line passing through the point 
and having slope m is
Given slope m=0 and given point is is (-2,-2)
therefore equation of the straight line is
Therefore the straight is parallel to negative x-axis(y=-2)
Answer:
The answer is 6
Step-by-step explanation:
A=½(b1 + b2) h
we substitute
Area=75
the two bases are 10 and 15
75=½(10+15) h
75=½(25)h
75=(1*25/2)h
75= 25h/2
75/1= 25h/2
25h*1= 75*2
25h= 150
we divide by 25
25h/25= 150/25
h=6
