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

to find the y- intercept, let x = 0, in the equation and solve for y

0 + 12y = 60 ( divide both sides by 12 )

y = 5 ← y -intercept → A

assuming the points are (1, 1 ) and (2, 8 )

to calculate the slope m use the gradient formula

m = = 7 ( none of the stated answers )

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
