Best ResponseYou've already chosen the best response.0write it in the form (x/a)+(y/b)=1, then convert it into the form y=mx+c, you have your slope

Best ResponseYou've already chosen the best response.0a and b are intercept on x and y axis respectively.

Best ResponseYou've already chosen the best response.0i still do not get it can you explain?

Best ResponseYou've already chosen the best response.0you can write a equation in intercept form, if a is intercept on x axis and b on y, than you can write a line as (x/a)+(y/b)=1 is this point clear?

Best ResponseYou've already chosen the best response.0Slope intercept form is y = mx+b where b is the yintercept

Best ResponseYou've already chosen the best response.0Since the y intercept is given to be 4/5, we can say b = 4/5 and y = mx+b becomes y = mx + 4/5

Best ResponseYou've already chosen the best response.0The xintercept is given to be x = 2, so essentially, x = 2 and y = 0. Plug these values in and solve for m y = mx + 4/5 0 = m(2) + 4/5 0 = 2m + 4/5 0  4/5 = 2m + 4/5  4/5 4/5 = 2m 2m = 4/5 m = (4/5)*(1/2) m = 4/10 m = 2/5 This means that the equation of the line in slope intercept form is \(\Large y = \frac{2}{5}x + \frac{4}{5}\)

Best ResponseYou've already chosen the best response.0so that is the final answer there is no more simplifying or anything

Best ResponseYou've already chosen the best response.0That's as simplified as it gets in that form

Best ResponseYou've already chosen the best response.0did you divide by two towards the end, im just trying to make sure that i understand the process

jim_thompson5910

Best ResponseYou've already chosen the best response.0i multiplied both sides by 1/2, which is the same as dividing both sides by 2, so yes

Best ResponseYou've already chosen the best response.0this was done to completely isolate m at the end

Best ResponseYou've already chosen the best response.0okay so if i messed up on typing in the problem how much would this affect the answer? I should just be able to plug the right number in right ?

Best ResponseYou've already chosen the best response.0You should be able to plug in each intercept and test if it works or not ex: plug in the xintercept: x = 2 and y = 0 and you should get a true equation also plug in the yintercept: plug in x = 0 and y = 4/5 and you should get a true equation

Best ResponseYou've already chosen the best response.0okay i plugged in three and then i have y=4/15x+4/5

jim_thompson5910

Best ResponseYou've already chosen the best response.0you multiply 3 by the numerator, not the denominator

jim_thompson5910

Best ResponseYou've already chosen the best response.0and once you plug in 3 for x, the x goes away

Best ResponseYou've already chosen the best response.0okay im confused again lol i thought that was slope intercept form

jim_thompson5910

Best ResponseYou've already chosen the best response.0\(\Large y = \frac{2}{5}x + \frac{4}{5}\) is slope intercept form

jim_thompson5910

Best ResponseYou've already chosen the best response.0and you're done because it cannot be simplified any more

Best ResponseYou've already chosen the best response.0yeah okay but that was for the problem i messed up on and typed the wrong number into. so now im struggling with the problem once i am supposed to multiple by 1/3

Best ResponseYou've already chosen the best response.0that is where i got the 4/15

Best ResponseYou've already chosen the best response.0oh so the problem at the very top is incorrect?

Best ResponseYou've already chosen the best response.0yeah i typed the wrong x intercept it was 3 not 2

jim_thompson5910

Best ResponseYou've already chosen the best response.0if the xintercept is 3 instead of 2, then you are correct in saying that the answer is \(\Large y = \frac{4}{15}x + \frac{4}{5}\)

Best ResponseYou've already chosen the best response.0okay i was thrown off a little because of the denominators cuz 15 is divisible by 5

jim_thompson5910

Best ResponseYou've already chosen the best response.0well you definitely got the right answer because \(\Large y = \frac{4}{15}x + \frac{4}{5}\) is fully simplified and it does have an xintercept of 3 and a yintercept of 4/5

Best ResponseYou've already chosen the best response.0if the y intercept was 2/5s adn the x intercept was three would the solution be 4/15x+2/5
