and what is the slope for this line equation?

Slope = m
= y2-y1\x2-x1
= -4-6/-3-2
= -10\-5
=2
note: / means divided by
the slope of y= 2\3x-4 is 2\3

Hi Meg!
I assume you're talking about the equation of a straight line, so, it would be something like:
y = ax + b (where a is the slope).
So, you should do this:
6 = 2a + b
-4 = -3a + b
Solving the system you'll find out that a = 2.
In the second case, the slope is a = 2/3.
Hope I've helped somehow.

slope of line through (2,6) and (-3,-4) is 2
& that of second one is 2/3

slope of a line with two points is (y2-y1)/(x2-x1)
(6-(-4)) / (2-(-3) = 10/5 = 2
The canonical form of a straight line is y = mx + b, where m is the slope.
So slope is 2/3
