How do you write the point-slope form of the equation that has a slope of -5/6 point (8,-4)

Step-by-step explanation:

the equation of a line in

point-slope form

is.

xy − y1 = m(x−x1)

where m is the slope and (x1 - y1 ) a point on the line

to calculate m use the

gradient formula

m= y2−y1

     x2−x1

let ( x1 , y1) =( 8, 5) and ( x2 ,y2 ) = (0, −4)

⇒ m= -4-5/0-8= -9/-8= 9/8

using m= 9/8 and (x1- y1) = (8,5) then

y-5= 9/8(x-8)

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
