Question

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

Answer 1

x + 2y = 5
2y = -x + 5
y = (-1/2)x + 5/2
so
m = -1/2
when x = 0, y = 5/2 (y intercept)

Answer 2

Thank you:)

Answer 3

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
