Answer:
y +2 = 2(x +3)
Step-by-step explanation:
The equation in point-slope form for a line with slope m through point (h, k) is ...
y -k = m(x -h)
The slope of your given line is the coefficient of x, -1/2. The slope of a perpendicular line will be the negative reciprocal of that: -1/(-1/2) = 2. So, you have m = 2, (h, k) = (-3, -2), and your desired equation is ...
y -(-2) = 2(x -(-3)) . . . . . . which can be simplified to ...
y +2 = 2(x +3)
Answer:
76$
Step-by-step explanation:
114=.6y; y= original price
y=190, original price
190-114=76
Answer:
A
Step-by-step explanation:
work out price of each for one bottle
A) $12.60 ÷ 7 = $1.80
B) $10.98 ÷ 6 = $1.83
C) $18.10 ÷ 10 = $1.81
D) $16.38 ÷ 9 = $2.82
we can clearly see that A is the cheapest
The answer would be B. It gives you the slope and a point on the graph so use that to your advantage. All of the answers show the slope and the slope in the right place, so for now it can be any of them. Then we get to the point (10,-2). For point slope form you would switch the signs for both x and y. So the Y would now be +2 and x would be -10. Y goes together with y, and X goes together with x. In this case y+-y= slope(X+-x)
Substitute in for them. Y+2=3/5(X-10)
