The -4 would be your y-intercept and the 2x would be your slope. So you would put a mark on the-4 on the y axis and go up 2 and to the right 1 to plot your line. The second one would put your starting dot on the (0,0) and go up 2 and to the right 1 to get your line. Because you would look at the 2x as 2/1x.
Hope i could help
Answer:
$7244
Step-by-step explanation:
Step one:
Given data
Columbia Mirror and Glass pays Frank Griffin $2570 monthly salary plus a 6% commission.
If sales is $77,900
Required
Frank's take home
Step two
let us find the expression used to determine Frank's take-home pay
let the total be y
y= 2570+ 6/100*77900
y=2570+0.06*77900
y=2570+4674
y=$7244
Since represents the number of years passed since 2005, in 2005 we have , and in 2015 we have . Let represent the profits of Jones and Davis, respectively, at year y.
We have
Choosing the best company somehow depends on how much time you can wait: Jones start with a higher value (10 vs 8), but it has a descending trend, because the multiplicative factor goes to zero as t grows.
On the other hand, Davis starts with a smaller value, but tends to infinity as t grows.
So, if you need an immediate result, the most valuable company is Jones, otherwise you're certain can Davis will eventually become bigger.
More precisely, we have
So, after 11 years, Davis will overcome Jones.
Crossroads or maybe where scissors meet eachother at the middle point you could do either
