Question

Which is the equation of a line that has a slope of 1/2 and passes through point 0 , -2

Answer 1

The general equation of a line is y = mx + b
m is given as 1/2, so we have:
$y=\frac{1}{2}x+b$
Plugging in the given values of x and y, we get:
-2 = 0 + b
Therefore b = -2, and the answer is:
$y=\frac{1}{2}x-2$
