Question

A:x+y=6
B:y=2x+4
C:3x+y=9
D:y=-2(x-5)-6

Answer 1

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

Answer 2

d

Explanation:

first, use the slope formula to find slope

y1-y2/x1-x2

-6-8/5-(-2)

-14/7

slope is -2

so given this piece of info, the answer must be d because the slopes match

in the formula y=mx+b, m is the slope, b is the y-intercept
