Question

What is the slope-intercept form of the equation y - 7 = - 5/2(x + 4)?

o y - 2 = -5/2(x + 2)
o y + 7 = -x + 5/2
o y = - 4/7 + 2
o y = - 5/2x - 3

Answer 1

y=mx + c
this is slope-intercept form.. just see which of your equation looks like this..

Answer 2

Okay, I think it would be the second option then; y = 2/5x + 2.

Answer 3

Oh sorry, I'm wrong. I put the wrong choices by accident.

Answer 4

hmm ya i noticed your question gives a different answer

Answer 5

I fixed the original question options.

Answer 6

IMPORTANT LINE RELATED EQUATIONS TO KNOW AND MEMORIZE

slope formula
m= slope/ gradiant -- same thing
\[m=\frac{y_2-y_1}{x_2-x_1}\]

standard formula
\[Ax+By=C\]

point-slope formula
\[y-y_1=m(x-x_1)\]

slope-intercept formula
b= y-intercept -- in the form of (0,y)

\[y=mx+b\]

Answer 7

Okay, I think for this particular problem (in the original question), the answer is the third choice, since it is the only one in slope-intercept form and has a positive b. Am I correct?

Answer 8

nop.. its not 3rd check again what slope u have in question. and match it with the options.

Answer 9

not c,

slope is different than what's given

Answer 10

Okay, well, I first need to times /5/2(x + 4) right? I need to actually work out the problem rather than see which one it matches with?

Answer 11

I meant -5/2

Answer 12

I see now why it isn't the third one.

Answer 13

I would say the fourth one. -7 + 4 = -3 for b. Correct?
