okay guys can someone please help me. i will love you forever if you doooo.?

Question

its in alerbra 1. im currently getting a D+ in the subject, so as you can tell i dont really know whats going on. were doing it over lines, y-intercepts, slopes, things like that. i wasnt at school so i dont know how to solve these. gaaahhh. i need to get my grade up though because if i dont pass, i go to private school. yeah the ones with the uniforms AND NO BOYS!!!! okay so pleeeeeaaaasssseeee if you know how to help me, please do. ill do you a favor in return. im very desperate. so heres the question:

instructions- write an equation of each line:
35. A line passing though (6,0) with y-intercept of 2.
36. A line containing points (1,4) and (2,7)
37. A line passing through the origin and parallel to y = 2x + 6

okay so yeah if you have ANY idea, please share. because believe me im not going to get it right anyways. so even if you dont know i want to hear how you might THINK how to solve it. okay thanks so so so so much for reading this and even more if you help!!!!

Answer 1

35 solve for the equation y=mx+b (if this doesn't look familiar, go read your book!).

m is the slope of the line, b is the y intercept, so

y = mx + 2
0 = m*6 + 2
m = -1/3

thus, y = -1/3 *x +2

36

to calculate the slope, remember that it is the change in the rise (y) over the change in the run (x), so m = (7-4)/(2-1) = 3/1 = 3

so y = 3x + ?

using the first ordered pair, (1,4)

4 = 3*1 + ?

? = 1

the equation is y = 3x + 1 (test this with the second ordered pair)

37. A line parallel to y=2x+6 would have the same slope (6). A line passing through the origin would have a y-intercept of 0. so, the equation is

y = 2x

this is one of the most important lessons in algebra. take the time to read the book, it is worth it.

Answer 2

for numbers 35 and 36, you need to find the slope between the two points ( for number 36 its (1,4)(2,7) and for 35 its (6,0 and (0,2) Becuase (0,2) is the y intercept, or where the line crosses the y axis. Once you know both points you find the slope

m(the slope) = y(1)-y(2) y(1)- 2nd number in 1st point
----------- y(2)-2nd number in 2nd point
x(1)-x(2) x(1)-first number in 1st point
x(2)-first number in second point


you them use this formula

y-b = m(x-a)
you substute a and b for either of the two points
(a,b)
then add m
simplify
then you have your awnser

for number 37
its similar
parrelel lines always have the same slope
so your new line will have a slope of 2
becuase there is a 2 before the x
they then want you to create a line with that slope going through the origin
the origin is (0,0)
so put the 2 in the eq as m
y-b = m(x-a)

then add (0,0) as a and b
and simplify


hope this is easy to understand
if you have any more question message me
hope this helps

Answer 3

35. write the equation in the form y=mx+b. b is the y-intercept so plug in all your values: 0=m(6) + 2. you get m= -1/3. so your equation would be: y= -1/3x +2

36. first find the slope using the two points: the formula is the change in y/ change in x so that means:(7-4)/(2-1). your m = 3. put that in the y=mx+b equation: y= 3x+ b. the next step is to find what b equals, just pick one of the points to plug in: 4=3(1)+b so that you get b= 1. your final equation: y= 3x+1

37.parallel line means same slope: so m= 2. origin means (0,0). so your final equation y= 2x

Answer 4

35) y=mx+b 0=6m+b 2=m(o)+b 2=b 0=6m+2 6m=-2 m=-1/3
y=-1/3x+2
36) y=mx+b 4=m+b 7=2m+b 7-2m=b 4=m+7-2m -3=-m
m=3 4=3+b 1=b y=3x+1
37) parallel means same m (slope) y=2x+b 0=0+b b=0 y=2x

Answer 5

35.
36. m= 3 so... 4 = (1)(3) + b
b=1
y=3x +1
37. y= 2x

Answer 6

thats easy wuts ur aim give u a word doc.
