Choose the correct slope-intercept form of the following equation and identify the slope and y-intercept. x + 2y = 5

a.)2x + y = 3; m=2; b=3

b.)y = 3x + 2; m=-4; b=0

c.)y = -1/2x + 5/2; m=-1/2; b=5/2

x + 2y = 5

2y = -x + 5

y = (-1/2)x + 5/2

so

m = -1/2

when x = 0, y = 5/2 (y intercept)

Option d is correct because 2y=-x+5

divide by 2

y=-x/2+5/2

compare by y=mx+c

m=-1/2 and c=5/2
