Find the y-intercept and the slope of the line
y=-1/2-5/2x

-1/2=b   <--- y int.   y=-5/2x-1/2    slope= -5/2

Step-by-step explanation:

So the slope is -5/2x because its given

the original equation: y=-5/2x-1/2

if x=0,

y=-1/2  (0,-1/2)

enter this into the y=-5/2x+b

-1/2=b   <--- y int.

so the new equation is

y=-5/2x-1/2

y = 5x + 2

Step-by-step explanation:

x=0 y=2 => b=2

x = 1 y = 7 b=2 => m =5
