It’s it four I think hope it helps
Answer:
Step-by-step explanation:
Circle - A = πr²
Semi circle - A= 1/2 πr²
Trapezoid - A= 1/2 (base 1 + base 2 ) x height
Rectangle - length x width
Triangle - A= 1/2 base x height
Easy peasy
slope=(change in rise)/(change in run)
aka
slope between points (x1,y1) and (x2,y2) is
slope=(y2-y1)/(x2-x1) since y is rise/up and x is run/leftright
points
(-7,-9) and (-5,-8)
x1=-7
y1=-9
x2=-5
y2=-8
remember minusing a negative means addin a positive
slope=(-8-(-9))/(-5-(-7))=
(-8+9)/(-5+7)=1/2
slope=1/2
positive slopes go from bottom left to top right
since it is less than 1
it is more horizonal than vertical
