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
