Which equation represents a line that passes through (4,1/3) and has a slope of 3/4?
scoray [572]

Step-by-step explanation:

With this kind of problem, we're looking at an equation in the form

y - y1 = m(x - x1)

(m = slope)

so we can substitute m, y1, and x1 with the values we're given.

y - y1 = m(x - x1)

y - 1/3 = 3/4(x - 4)

Answer:

y - 1/3 = 3/4(x - 4)

poizon [28]

Answer:

x = 10

Step-by-step explanation:

=> 6x = 61 - 1

=> 6x = 60

=> x = 60/6

=> x = 10

One market sells a 3 kilogram bag of tortillas for 42 pesos and another sells 2 kilograms of tortillas for 26 pesos which unit p
Dafna1 [17]

Answer:

2 kilogram bag.

Step-by-step explanation:

To figure this out, we need to divide the price by the amount of kilograms. Lets start with the 3 kilo bag. Divide 42 by 3, let y equal the price per kilo

42/3=y

Divide

14=y

Now lets do the same with the 2 kilo bag. Divide 26 by 2. Let x be this number.

26/2=x

divide

13=x

The 2 kilo bag is better as its 13 pesos per kilo compared to the 3 kilo bag's 14 pesos per kilogram.
