Write an equation of the line that passes through (8,-4) and has a slope of -3/4

y=-3/4x-2

Step-by-step explanation:

put it in point slope form (y-y1)=m(x-x1) and plug on 8 for x1,-4 for y1, and -3/4 for m

y=-¾x+2

Step-by-step explanation:

Use the point-slope formula

y-y1=m(x-x1)

in other words

y+4=-¾(x-8)

Distribute next

y+4=-¾x+6

Isolate y

y=-¾x+2

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to
