Hello,
The points are:
(2,1); (1,5/3); (5,-1)
Bye:-)
Here's the right way:


Here's the way they want you to do it:



Answer:
Step-by-step explanation:
(a,9).......we dont know " a " (or x) but we do know y...it is 9
so sub in 9 for y and solve for x
y = 2x + 1
9 = 2x + 1
9 - 1 = 2x
8 = 2x
8/2 = x
4 = x <======= ur answer is D
Divide both the numerator and denominator by the GCD so it’s 12/1
Substitute the x and y values from (3,2).
Formula: y=mx+b
2= 3(3)+b
2-9= -7
y=3x-7
