The second one from the top shows a dilatation.
Answer:
m = -1/4
Step-by-step explanation:
4y + x = 8
Arrange the equation in a slope intercept form y = mx+b, where m is the slope
4y + x = 8, subtract x from both sides
4y = -x +8, divide both sides by 4
y = -x/4 + 8/4 , simplify
y = -x/4 + 2, compare this to the general form y=mx+b and we see that the slope m = -1/4
Well if 13x9=117 so what's the units if 13x9 is 117
Well, we see that it is a straight line
so the derivitive would be perpendicular
5/4 times what=-1
-4/5
the slope is -4/5
