Question 366501
<pre><font size = 3 color = "indigo"><b>
Hi, 
Slope -2 Or -2/1 tells us as x increases by one, y decreases by 2 Or that
as x decreases by one, y increases by 2
( 4, 4)
(-3, y)
Here, x has decreased by 7, therefore y must increase by 14 so as to satisfy the slope conditions (14/-7) = - 2/1
(-3, 18) is a point on this line
y = 18

y = mx + b  (y =-2x + b   4 = -2*4 + b   b =12)
y= -2x + 12
