On January 22, 1945, the temperature in Spearfish, South Dakota, fell from 54 degrees Fahrenheit at 9 am to -4 degrees at 9:27 am. how many degrees did it fall?

58

Step-by-step explanation:

Use a number line.

-4 + 4 = 0.

So, you already have 4 Fahrenheit.

Then, add the distance of 54 from 0 to 54.

4 + 54 = 58.

That is your answer, here to help!

50*10 is greater

step-by-step explanation:

if you add the zero from 10 to 50, it will give you a bigger number.

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
