http://prntscr.com/8k9044 Answers: y – 4 = -2(x + 3) y + 4 = -2(x – 3) y + 3 = -2(x – 4) y – 3 = -2(x + 4) This one im not sure
@BAdhi
cant see the images :(
why :'[
@BAdhi did it let you view them?
Use the point-slope form of the line, and work on the dot. The point slope form is: (y-y1)=m(x-x1) where m=slope of the line, (x1,y1) is ANY point on the line. First find the slope of the line: we see that for every 2 units in x, y \(decreases\) by 4 units, so the slope is -4/2=-2. So we have an equation of (y-y1)=m(x-x1) where m=-2..................(1) The next step is to find a point (ANY point) on the line, the recommended one is shown in the graphic, (-4,3). So substitute y1=3, x1=-4 into the above equation (1) and find the equation to the given line.
so the answer is c?
Close, but not quite: (x1,y1)=(-4,3) so x1=-4, y1=3 Substitute into (y-y1)=-2(x-x1) and see what you get. Also, when checking answers, please mention the value of the answer, not just the letter. The fact of using the letters makes it look like a guessing game, which math is not.
so it would be y – 3 = -2(x + 4)
@Mehek14
@FitzIncorporated
Exactly, y – 3 = -2(x + 4) is correct.
@mathmate are my answers for the other 2 correct?
So what is your answer for the second one?
im not to certain about that one
I rephrase. We have already looked at the third one. The first one you gave an answer, but it says all that applies, so there could be more than one choice (makes guessing more difficult, DO NOT guess). The second one is the one you have not provided me with an answer to check. For the first one, you need to examine the truth value of each of the four statements and answer accordingly. Examine them one by one, and look up meaning of words that you don't understand. Post if you still have difficulties. It is always a good idea to review your lessons before starting exercise. It will always save you time and frustration, AND get better grades.
