Question 388386
1. Determine the slope and y-intercept of the graph: 3x + y = 8
         I got slope = 3, y-intercept = 8? right or wrong? if so please explain

3x + y = 8
add -3x to both sides
y =-3x+8
compare with y = mx+b
slope = -3
y intercept = 8


2. Determine the slope and y-intercept of the graph: -x + 2y =4.
         I got slope = -1/2, y-intercept = 2? same as above

-x+2y=4
add x to both sides
2y=x+4
/2
y=1/2 *x+2
m= 1/2 
y intercept = 2
