The equation for a line is in the format:
y = mx + b
where m is the slope and b is the y-intercept. You have been given that the slope is -1/2 and the y-intercept is (0,3) which means it crosses the y-axis where y = 3. So, you write the equation as:
y = mx + b (m = -1/2 and b = 3)
y = (-1/2)x + 3

Equation for slope - y =mx + c
Slope=M, so therefore -1/2 is the slope
Y intercept=C, so therefore 3 is the y intercept
y = -1/2 (x) + 3

The equation for a line is y = mx+b where:
m = slope
b = y-intercept (the y-intercept is the coordinate of y when x=0)
So your equation is:
y = -1/2x + 3

equation of a straight line is Y = mX + c, where m is the slope and c is the y-intercept, with Y as the y-axis and X as the x-axis.
hence, the equation of the line is Y = -1/2x + 3

These kinds of problems are solved using the equation
y=mx + b, where m is the slope and b is the intercept.
You know that when x=0, y=3. Plugging that in:
y=mx + b becomes
3 = -0.5 times 0 + b
So, 3 = 0 + b
Which means that b=3.
Now, we know the equation:
y = -0.5x + 3

to write a slope intercept form y = mx + b, you need the slope and y-intercept.
m = slop
b = y-intercept
they give you both, just plug them in
y = (-1/2)x + 3

The form is y=mx+b
m is your slope
y=-1/2x+b
to solve for b
put in the point (0,3)
3=-1/2*0+b
3=b
therefor
y=-1/2x+3

the equation has the form y=-1/2 *x+b
you replace x by zero and y by 3 you obtain
3=1/2*0+b so b=3
and y= -0.5x +3 0.5=1/2
