Slope = 2/5; passes through (-3,1)

nydimaria [60]

Presumably we're after the line with that slope through that point. In general the line through $(a,b)$ with slope $m$ is

$y-b = m(x-a)$

Here we have $a=-3, b=1, m=\frac 2 5$

$y - 1 = \frac 2 5 (x--3)$

$y = \frac 2 5 x + \frac 6 5 + 1$

$y = \frac 2 5 x + \frac{11}{5}$

Check: The slope is clearly $\frac 2 5$
so we check

$y = \frac 2 5 (-3) +\frac{11}{5} = \frac 5 5 = 1 \quad\checkmark$

In 1985 there were 275 cell phone subscribers in the small town of China grove. Subscribers increased by 40% each year after 198

emmasim [6.3K]

1985year ->275cell phones->100%
1994year -> x cell phones ->100%+360%
40% • (1994-1985)= 40% • 9= 360%

275 cell phone 100%
X cell phones. 100+360%=460%
x=275•460%/100%
x=12420/100
x=1265
99% sure this is a correct answer

x=275 • 460%/100%
x=12,420/100
x=1265

1994-1985= 9 yrs • 40%= 360%
