The equation of a line in slope form is y = mx + b where m is the slope, which is given as -1/2, and b is the y intercept, which is given as (0, 3). Since 3 is the y value just plug in the numbers: y = -1/2x + 3. The negative sign before 1/2 means the line is decreasing.

The fomula is y=mx+b m=slope, Plug in the coordinates (0, 3) and the slope in the equation to solve for b (the y intercept).
3 = -1/2(0) +b so b = 3
y=-1/2x+3

this can be is found by equation:
y=mx+c,
where m=slope and c= y-intercept.
so,y=mx+c
y= -x/2+3
2y=-x+3
x+2y=3
so,the equation of the line having slope -1/2 and y-intercept is:
x+2y=3
