Lesson 10: linear functions unit test , .

for the data in the table, does y vary directly with x? if it does, write an equation for the direct variation.

x y
8 11
16 22
24 33

a. yes; y =2.75x
b. yes; y=0.6875x
c. yes; y=1.35x
d. no; y does not vary directly with x.

if you guys have the rest of the answers to the test i'd appreciate that so giving 28 points for this question!

Step-by-step explanation:

To find the equation, we need to use two points: (8,11) and (24,33).

Then, we find the slope

Now, we use the point-slope formula

Notice that the formula has the form , that means variables are not directly proportional, because that relation is shown by the form .

Therefore, the right answer is D.

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
