Answer:
The equation of the line would be y = 1/8x - 3
Step-by-step explanation:
to find the slope intercept form of the line, you must first find the slope. You can do this using the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (-2 - -4)/(8 - -8)
m = 2/16
m = 1/8
Then you can use this slope along with either point in point-slope form. Then solve for y.
y - y1 = m(x - x1)
y + 4 = 1/8(x + 8)
y + 4 = 1/8x + 1
y = 1/8x - 3
B. because you do 16*2*h + 8*2*h and you get 128 + 64 = 192

Step-by-step explanation:
Answer:
23x2+8xy−57y2
Step-by-step explanation:
(5x)(5x)+(5x)(7y)+(−7y)(5x)+(−7y)(7y)+−2x2+8xy+−8y2
=25x2+35xy+−35xy+−49y2+−2x2+8xy+−8y2
Combine Like Terms:
=25x2+35xy+−35xy+−49y2+−2x2+8xy+−8y2
=(25x2+−2x2)+(35xy+−35xy+8xy)+(−49y2+−8y2)
=23x2+8xy+−57y2
