Does the slope depend on how the y
of a straight line changes or on both x and y?
For example, A straight line 2x - y = 0
passing through origin has a slope m = 2
.
Now, when
x = 1 | y = 2 x = 2 | y = 4 x = 3 | y = 6
It looks like the value of y
is increasing by 2, which is confusing me because m = 2
.
In case 2, A straight line 2x + 3y = 18
has slope m = -2/3
and, when
x = 1 | y = 5.33 x = 2 | y = 4.66 x = 3 | y = 4
In this case it looks like the y
is decreasing by -2/3
so, does the slopes of a straight line only effect y
?
