Would someone mind answering this for me? you

(a) m =

calculate the slope (m) using the ' gradient formula '

m =

let (x₁, y₁) = (8, 9) and (x₂, y₂) = ( - 2, 4)

m = = =

(b) y - 9 = (x - 8)

the equation of a line in ' point- slope form ' is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

choose any of the 2 given points for (a, b) → (8, 9)

y - 9 = (x - 8) → " point- slope form"

(c) y = x + 5

the equation of a line in ' slope-intercept form ' is

y = mc + c

where m is the slope and c the y-intercept

expand and simplify the point- slope equation

y - 9 = x - 4

y = x - 4 + 9

y = x + 5 → " slope- intercept form"

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
