Answer:

y = 3x+4

y = -2x-1  

Step-by-step explanation:

slope intercept form

y= mx+b  where m is the slope and b is the y intercept

to get in this form we solve for y


y -3x =4

add 3x to each side

y-3x+3x = 3x+4

y = 3x+4   where 3 is the slope and 4 is the y intercept


2x+1 = -y

flip the sides

-y = 2x+1

multiply  by -1

-1* -y = -1 * 2x + -1 *1

y = -2x-1    the slope is -2 and the y intercept is -1
