Which of the following is the equation of the line that passes through the point begin (-6,1) and has a slope of -1/2

18

Step-by-step explanation:

Area = h*(b1+b2)/2

well b1 is 4 and b2 is 8 because 4+4

to find h you need to know pythagorean theorem which is a^2+b^2=c^2

well c is always the longest measurement and directly across from the right angle so in this case it is 5. a is just the base which is for so you can just plug that into a calculator to get b as 3.

b is your height so now you have everything you need to know in order to get the answer

h = 3

b1 = 4

b2 = 8
