y=mx+b
m= slope; b= y-intercept
m= -1/2 (down one, two to the right); b= 3 (where the line crosses the y-axis)
substitute
y= -1/2x + 3

y = (-1/2) x + 3 = 3-x/2

Y=mx+b is the slope-intercept form. Since you're given m and b, this is extremely easy and the answer is y=1/2x+3.

Well, first the answer is
y=m+b which means that y=1/-2+3
Y Is 3 X is your point when you rise/run 1/-2 (-1,3).

the generaic formula is y-mx+b.
so:
y=-1/2x+3
just substitute the numbers in with their corresponding variables.
