maria [59]3 years ago

Answer: D. 2

Step-by-step explanation:

Given

y-1=2(x--2)

Change signs

y-1=2(x+2)

Expand parenthesis

y-1=2x+4

Add 1 on both sides to isolate "y"

y-1+1=2x+4+1

y=2x+4

So the slope is 2

Hope this helps!! :)

3. Write an equation in slope-intercept form of the line that passes
kirill115 [55]

Answer:

B. y = 2x - 9

Step-by-step explanation:

All of the answer choices has a slope of 2, but B is the only answer choice that has (4,-1) on its line.

You can tell by plugging the point into the equation and seeing if the result is true.

y = 2x - 9

-1 = 2(4) - 9

-1 = 8 - 9

-1 = -1

Rewrite the equation to isolate the variable.. df= g- 10 for d
ehidna [41]
Df = g - 10

To solve for d, divide both sides by f.

df / f = (g - 10) / f

d = (g - 10) / f

I hope this explains it.

rjkz [21]
Not sure about the first one but the second one is option c (or -3). You just have to factor and find the solutions (so it would be -7 and 4 and then u just add them)

For question 39 the answer is c
