Answer:
Using the two marked points we see that the slope is -3 and the y-intercept is 1 so the answer is y = -3x + 1.
Answer:
25x - 45
Step-by-step explanation:
5(5x - 9)
Distribute
5*5x - 5* (9)
25x - 45
11=5.5
6=x
11/5.5=6/x
11/5.5=6/3

Answer:
y=x and y=1
4 x
Step-by-step explanation:
We know,
'Direct Variation function' is the function where two quantities vary directly i.e. variables x and y are said to be directly varying if 'y=kx' where k is the constant of variation.Thus, from the options, we see that the function,
y=x
is varying directly with the constant of variation i.e. k = 1.
y= 1
4 x
is also varying directly with constant k=1
