slope = (1 - -2)/(1- - 4)
slope = 3 / 5
General formula for a line is y = mx + c
So inserting the slope it becomes
y = (3/5)x + c
To find the equation of the line take any point and substitute it coordinates in. Take say (-4 , -2)
-2 = (3/5)(-4) + c
-2 = -12/5 + c
c = -2 + 12/5
c = 2/5
so y = (3/5)x + 2/5
or 5y = 3x + 2
Usually written as
3x - 5y = -2

The slope is:
(1 - (-2)) / (1 - (-4))
= (1 + 2) / (1 + 4)
= 3 / 5.

slope = ( 1-(-2)) / ( 1-(-4))
= (1+2) / (1+5)
= 3/5

slope=(y2 - y1)/(x2 - x1)
=(1-(-2))/(1-(-4))
=3/5=.6
