The table shows the median home prices in Florida. What is the equation of a trend line that models a relationship between time and home prices? Use the equation to predict the median home price in 2020. Year 1940 1950 1960 1970 1980 1990 2000 Median Price($) $20,200 $39,900 $50,400 $62,800 $89,100 $98,700 $119,000 A. y = 1646.67x + 20,200; $151,900 B. y = 49.4x + 20,200; $119,000 C. y = 49.4x + 20,200; $151,900 D. y = 1646.67x + 20,200; $119,000
@ajprincess this and 4 more that's it
what's ur answr?
sorry but I dunno this one!
hmm np.:)
yeah, so which one do u think
let the equation be y=mx+c nw consider the points (1940, 20200) and (2000, 119000) hope u can find m from this.
ok 1 sec
1646.67
yup
so what's the answer now! A or D
median=(2020-1940)*1646.67+20200
how did u get this formula
i too am nt sure. jst a sec. let me figure it out if it is the right one.
btw the answer is 1747733.6!!!
so noP
check out the answer u got
it comes as 151933.6
oh okay fine
but how did u get the formula
oh okay I see what u did
What are the intercepts of the equation? Graph the equation. -3x + 4y = -12
i assumed the equation as y=mx+c.
C. x-intercept: (4, 0) y-intercept: (0, –3)
is this right!
x-the differnce between the yrs. for the first point (1940-1940=0) so the coordinate of the first pont will be (0,20200), consider the last point (2000-1940,119000)=(60,119000). using these two points i found the equation.
oh okay
can u check the other question is this the right graph
i am chcking it right nw
tyt
r u sure abt the y-intercept?
A. x-intercept: (–3, 0) y-intercept: (0, 4) B. x-intercept: (4, 0) y-intercept: (0, –3) C. x-intercept: (4, 0) y-intercept: (0, –3) D. x-intercept: (–3, 0) y-intercept: (0, 4)
sorry. made a mistake. ur both intercepts r right:)
and was the graph right
yup right:) the graph for the first question wont be a linear one.
the question is this What are the intercepts of the equation? Graph the equation. -3x + 4y = -12
for that ur answer is right:)
I meant the other one. median ques
this is last question Write the equation in slope-intercept form. What are the slope and y-intercept? -11x + 9y = -12 A. y = 11/9x - 4/3 slope: 11/9 y-intercept: 4/3 B. y = -11/9x + 4/3 slope: 11/9 y-intercept: 4/3 C. y = 11/9x - 4/3 slope: 11/9 y-intercept: -4/3 D. y = 11/9x + 4/3 slope: 4/3 y-intercept: 11/9
write the eqn in the form y=mx+c
m-slope. c-y-intercept
9y= 11x-12
divide both sides by 9. then u will get the equation in the form y=mx+c
have u got it?
it's C
slope 11/9 and Y intecept is -4/3
yup:)
okay thnx that's it for now when I will start the rest I will hit u up
good work. keep it up:)
thank u so much u really helped
welcome. glad to hear.:)
