Answer:
English translation please.....
First find the slope of the line that passes through (4,-1) and (-2,3) by calculating "change in y" / "change in x"
So slope = -4/6 = -2/3
Remember the format y = mx + b?
So pick any of the two coordinates (I'll use (4,-1)) and sub in what you can.
-1 = -2/3(4) + b
Solve for b and you'll get 1.66666.... aka 1 2/3
So the equation is y = -2/3x + 5/3
Now for the next question.
So 5/2.5 = y/10
cross multiply and simplify and you'll get y = 20
The answer is 18 1,2,3,6,9,18
