HELP ME WITH THIS PLEASE PLEASE SHOW ME THE FORMULA FOR LETTER C​

see explanation

Step-by-step explanation:

1

(a)

Calculate slope m using the slope formula

m =

with (x₁, y₁  = (8, 3) and (x₂, y₂ ) = (10, 7)

m = = = 2

(b)

Given a line with slope m then the slope of a line perpendicular to it is

= - = -

(c)

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - , then

y = - x + c ← is the partial equation

To find c substitute (8, 3) into the partial equation

3 = - 4 + c ⇒ c = 3 + 4 = 7

y = - x + 7 ← equation of perpendicular line

2

(a)

with (x₁, y₁ ) = (3, 5) and (x₂, y₂ ) = (4, 4)

m = = = - 1

(b)

= - = 1

(c)

y = x + c ← is the partial equation

To find c substitute (3, 5) into the partial equation

5 = 3 + c ⇒ c = 5 - 3 = 2

y = x + 2 ← equation of perpendicular line

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
