Put equation into slope intercept form

11- y= -x - 7

12- y= 3x + 17

14= y= -4x+5

15= y= -3/5x + 3

Step-by-step explanation:

11- y+x=-7

move the variable to the right-hand side and change its sign

y=-7-x

use the commutative property to reorder terms

y=-x-7

12- y-  3x = 17

Move variable to the right-hand side and change its sign

y=17+3x

reorder terms

y=3x+17

14. -2y= 8x-10

change signs on both sides

2y=-8x+10

divide both sides by 2 to get Y isolated

y= -4x+5

15. 3x + 5y = 17

move the variable to the right-hand side and change the sign

5y=15-3x

to isolate the y, we need to divide each side by 5

y= 3- 3/5x

now we re-order the terms

y= -3/5x + 3

so, converting firstly the mixed fractions to improper fractions and then "adding".
