4) fifteen less than y is 32
15 - y= 32
15 - (-17)= 32
two negatives become positive so 15+17= 32

Answer
Answer: 0.4
Step-by-step explanation: Divide 2.4 by 6.
Hope this helps you out! ☺
The linear rule should look like this y=a*x+b
As the function graph goes through the (0,0) point, the equation 0=a*0+b <=> b=0 must be true.
Now we only need to find a, using one of the points given. With (-4, 16):
16=-4*a <=> a=16/-4 <=> a= -4
So the rule looks the following way:
f(x)= -4*x
Y2-Y1/X2-X1 = 7-22/1-4 = -15/-3 = 5
y=5x+ 0
