help please
3 years agoLaunch Area:___(1, 2)___ Point A:___(0, 3)___ Point B:___(-3, 0)___ Point C:___(-1, -4)___ 2. Determine the equation of the line, in standard form, that will get your spacecraft from the Launch Area to Point A.
3 years agoi know the answer is Y = 3 – x but could you explain the steps
3 years agoWhat are the boxes between 3 and x?
3 years ago-
3 years agooh ok I see it now. Well you would just use the slope formula (y-y/x-x) to find the slope, which would turn out to be 1, and then the y-intercept is given, +3
3 years agoWhen put into slope intercept form, it would be y = x + 3 Then you have to convert it to standard form so... Subtract y from each side to get ___ = x + 3 - y Then Subtract 3 from each side So you'll have: x - y = 3
3 years agooh ok could i get help with one more since its like the same question
3 years agoSure lol, I think I did this same question in my class
3 years ago4. Determine the equation of the line, in slope-intercept form, that will get your spacecraft from Point B to Point C. Y = -2 x - 6
3 years agocan yah show the steps please
3 years agoYes, hold on. Oh and I just went and checked the work that I had submitted when I was on that, I told you the slope for the first problem was 1, but it's actually -1 sorry
3 years agooh ok
3 years agothe first one in standard form is x + y = 3
3 years agofor your first question, you say **i know the answer is Y = 3 – x *** that is true. but standard form is Ax + By = C where, if at all possible, A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1 in other words, start with y=-x +3 (this is slope-intercept form) add +x to both sides to get x+y = 3 (this matches Ax + By = C, with A=1, B=1 and C=3 )
3 years agoi think i understand the concept when you guys put it like that thank you all
3 years agoNp :) do you still need help with the problem regarding points b and c?
3 years agowhat about the second one ??
3 years agoyeah plx
3 years agoPoint B:___(-3, 0)___ Point C:___(-1, -4)___ first, find the slope. Do you know how to do that ?
3 years agolet me think one sec plx
3 years agoslope is change in y divided by change in x find "change in y" then find "change in x" then write the fraction
3 years ago-2
3 years agoyes. I assume you can "show your work", which is (0- (-4)) / (-3 -(-1)) = 4 / -2 = -2
3 years agoYup. Now if you fill out a T chart, you can figure out what the y-intercept is.
3 years ago-6
3 years agonow all you have to do is fill in your data where the variables are y=mx+b y=-2x-6
3 years agooh ok so through all does steps showed how we got y=-2x-6
3 years agoyup
3 years agolet me try to right it out how it would look one sec
3 years agook got it thx
3 years agoto find the equation use y - y0 = m(x - x0) where (x0,y0) is a point on the line. If you pick point B Point B:___(-3, 0)___ then x0= -3 and y0= 0 (and m is the slope= -2) y - 0 = -2(x - (-3)) y = -2x - 6
3 years agowell that sums stuff up
3 years agothx again have nice day
3 years agohave a nice day too c: let me know if you need anymore help since we might be covering the same material
3 years agook ttyl
