Pls help I’m doing an exam

y=2x+19

Step-by-step explanation:

m=2

(-8,3)

y=mx+b

3=2(-8)+b

3=-16+b

b=16+3

b=19

so the y-intercept is 19

the full answer would be

y=2x+19

hope it helped you in the exam

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
