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

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
