Three snack bars contain 1/5,0.22,and 19% of their calories from fat. which snack bar contains the least amount of calories from fat ?

The answer is 19%

Step-by-step explanation:

In order to determine the snack bar with lowest calories from fat, we have to express the three values in a same notation way.

First value is expressed in fraction, second one in decimal and the last one in percentage.

Which one is the easiest way? The easiest way is in percentage notation because we only have to multiply the value by 100.

So, the values and will be multiplying by 100. The last value is already in percentage notation.

Then:

%

%

%

Finally, the snack bar, that it contains the least amount of calories from fat, is the last one with 19%.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
