Question

How do i do this pls help me

standard form (ax + by = c) to slope-intercept form (y = mx + b)

x-7y= -49 (ANSWER?)

Answer 1

`y = (1)/(7) x + 7`

Explanation:

x-7y = -49

i) move x to the right-hand side and change its sign

-7y = -49-x

ii) change the signs on both sides of the equation

7y = 49+x

iii) divide both sides of the equation by 7

`(7y)/(7) = (49)/(7) + (x)/(7)`

`y = 7 + (1)/(7) x`

iv) use the commutative property to reorder the terms

* commutative property: a+b = b+a

`y = (1)/(7) x + 7`
