2x20
1x40
4x10
5x8
All integers these multiply to 40
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
Answer:
1. Strange
Step-by-step explanation:
Answer:
r = - 11
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to - 4
m =
with (x₁, y₁ ) = (4, 5) and (x₂, y₂ ) = (8, r)
m = = = - 4 ( multiply both sides by 4 )
r - 5 = - 16 ( add 5 to both sides )
r = - 11
Answer
No
Step-by-step explanation:
Since you 4x3=12 3x3 = 9
