What is the y-intercept of 6x+ 12y= 60? a. 5 b. 10 c .60 what is the slope of the line that contains the points (1, −1) and (−2, 8)? a. −3 b. 7 over 3 negative c. 1 over 3 negative

Problem 1

Plug in x = 0 and solve for y to get the y intercept

6x+12y = 60

6(0)+12y = 60

12y = 60

12y/12 = 60/12 ... divide both sides by 12

y = 5

A) 5

Problem 2

Use the slope formula.

The two points are (x,1, y1) = (1, -1) and (x2, y2) = (-2, 8)

m = (y2-y1)/(x2-x1)

m = (8-(-1))/(-2-1)

m = (8+1)/(-2-1)

m = 9/(-3)

m = -3

A) -3

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
