Can someone mr in this multi answer question

A, C and D

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

here m = - 3, thus

y = - 3x + c ← is the partial equation

To find c substitute (- 1, 4) into the partial equation

4 = 3 + c ⇒ c = 4 - 3 = 1

y = - 3x + 1 ← in slope- intercept form → C

Add 3x to both sides

3x + y = 1 ← in standard form → A

The equation of a line in slope- intercept form is

y - b = m(x - a)

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

here m = - 3 and (a, b) = (- 1, 4), thus

y - 4 = - 3(x + 1) ← in point- slope form → D

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
