The answer if I am not mistaken would be B because the numbers are increasing by 2.
1. X1 Y1. X2, Y2
(-1,-6). ( -4,3)
Formula for slope which is m
Y2 -Y1 divide by X2-X1
3- -6/ -4 - -1= 9/-3= -3
So M = -3
Y=mx+b
-6= -3 (-1) +b
-6= 3+b
-3=-3
-9=b
Answer Y= -3x-9
2. X, Y
(-5,13)
Y=mx+b
13= 10+b
-10=-10
3=b
Answer C y= mx+b
y=-2x+3
3. (X1,Y1). (X2,Y2)
(3,-4). (5,-6)
Formula for m which is slope y2-y1 / x2-X1
-6- -4 / 5-3 = -2/2= -1 so m = -1
X, Y
(3,-4)
Y=mx+b
-4= -1(3)+b
-4= -3+b
+3=+3
-1. = b
Y= m x+b
-4= (-1) 3 +b
-4= -3. + b
+3= +3
-1. = b
Answer A y= -1x-1
slope-intercept formula: <em>y = mx + b</em>
<em>m</em> is the slope
<em>b</em> is the y-intercept
to find the <em>slope</em>, you would use rise over run ( 
). start at -5, where the line intersects at the y-axis and go up 2 and 1 right. this would be your slope 
or 2. to verify that this is the slope, every single dot on the line rises at 2 and goes 1 right.
to find the <em>y-intercept</em>, you would look at where the line intercepts at the y-axis. so, -5 would be the y-intercept.
plug the numbers into the slope-intercept formula, and your final answer is:
y = 2x - 5
