Answer:
90
Step-by-step explanation:
1/3 BH = 1/3(30)(9) = 90
I take the points that you gave. Let named A(0,-3) and B(2,1)
The slope coefficient is S= (yb-ya)/(xb-xa)
S= (1-(-3))/(2-0) => S= (1+3)/2 = 4/2= +2 => S= +2
The correct answer is positive slope
Good luck!!!
4 x 7= 28
BTW no calculator. Did it in my head. Hope this helps!
