(15,-10) (17,2)
(2+10)/(17-15)= 12/2 = 6
The slope is 6
If you would like to know if (0, 3) is a solution to the equation y = x + 3, you can find this using the following step:
(0, 3) = (x, y)
x = 0
y = 3
y = x + 3
3 = 0 + 3
3 = 3
Result: (0, 3) is a solution to the equation y = x + 3.
-sin(-x)/cos(-x)*cos(-x)/sin(-x)
Simplifying, we get 1
two pairs of parallel sides are equal
