a: x+y=6
b: y=2x+4
c: 3x+y=9
d: y=-2(x-5)-6

D

Step by step explanation:

The slope of your line is negative.

The y intercept, b is 4

The slope, m is -2

Using the formula y = mx + b

Your equation should be y = -2x + 4

However, it is not clearly written like that in any answer choice. Therefore, we have to completely put all the answer choices in slope intercept form.

D is y = -2(x - 5) -6

Distribute

y = -2x + 10 - 6

y = -2x + 4

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

pls mark as brainliest

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
