The line thru (-3,0) and (-6,5) has this slope:
5-0 5
m = ----------- = ------- = - 5/3
-6-(-3) -3
The y-intercept of the desired line is simply (0,0), and so b = 0 and the equation of this line is
y = (-5/3)x
C because it is to the nearest tenth I think
A product is negative when the number of negative numbers in the multiples is odd.
Therefore, options A and C gives negative products.
