Which equation represents the line that passes through the points (–3, 7) and (9, –1)?
galben [10]

Answer:

Step-by-step explanation:

first, we find the slope

slope = (y2 - y1) / (x2 - x1)

(-3,7)....x1 = -3 and y1 = 7

(9,-1)...x2 = 9 and y2 = -1

now we sub

slope(m) = (-1 - 7) / (9 - (-3) = -8 / (9 + 3) = -8 / 12 reduces to - 2/3

y = mx + b

slope(m) = -2/3

use either of ur points...I will use (-3,7)...x = -3 and y = 7

now we sub and find b, the y intercept

7 = -2/3(-3) + b

7 = 2 + b

7 - 2 = b

5 = b

so ur equation is : y = -2/3x + 5 <===

James works in a sporting goods store and earns $324 a week and 5% of his sales. One week James earned $432. What were his sales
Bogdan [553]

Answer:

His sales that week were $2,160.

Step-by-step explanation:

First, you have to subtract $324 from the amount he earned that week, to find the 5% he got from sales:

$432-$324=$108

Now, you know that he received $108 that represent 5% of his sales and you can use a rule of three to find the amount that represents 100% which would be his sales that week:

 5%   →    108

100% →      x

x=(100*108)/5=2160

According to this, the answer is that his sales that week were $2,160.
