Answer:

Step-by-step explanation:
The equation of a line is given in the form  
Where
m is the slope with formula  
and
b is the y-intercept [y axis cutting point of line]
Given the two points (0, -2) and (6,0),
x_1 = 0
y_1 = -2
x_2 = 6
y_2 = 0
Now, we find m using formula:

Now we have

Finding b, we plug in any (x,y) point. Lets put (6,0) and find b:

Thus,
equation of line =
