Determine whether the following is a function or not. EXPLAIN WHY

Yes! It's a function BECAUSE none of the y values repeat for different x-values.

Hope this helps! Comment if you have questions.

(-6,0)(-3,-1)
slope = (-1 - 0) / (-3 - (-6) = -1 / 3

y = mx + b
slope(m) = -1/3
(0,-2)...x = 0 and y = -2
sub and find b, the y int
-2 = -1/3(0) + b
-2 = b

so ur equation is : y = -1/3x - 2u got it right...and u did get -2 as the y int...because in y = mx + b form, the number in the b position is ur y int
