Review: find the slope for the following situations. a. given the equation y = 5x + 1 b. given the equation 2x + y = 6 c. given the points: (2, 3) and (5, 9)

Part 1) The slope is

Part 2) The slope is

Part 3) The slope is

Step-by-step explanation:

Part 1) we know that

The equation of the line into slope intercept form is equal to

where

m is the slope

b is the y-coordinate of the y-intercept

In this problem we have

so

the slope is

Part 2) we know that

The equation of the line in standard form is equal to

where

the slope is equal to

in this problem we have

so

substitute

Part 3) we know that

The formula to calculate the slope between two points is equal to

we have

Substitute the values

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
