X + 4y = 9 Convert to slope / intercept form:-
y = (-1/4)x + 9/4
so the line perpendicular to this will have a slope -1 /(-1/4) = 4
so our equation will be y - y1 = 4(x - x1) where x1y1 is a point on the line.
x1 = 8 and y1 = -3:-
y - -3 = 4(x - 8)
y = 4x - 35
-4x + y = -35 is the answer

Answer:
Step-by-step explanation:
7 + 3 + 5 + 15 = 30
The answer is A. U basically divide the price with the amount of item and pick the cheapest one :)
5x-1= 26
5x-1+1= 26+1
5x= 27
Divide by 5 for 5x and 27
5x/5= 27/5
x= 27/5
Answer is x= 27/5 - A)
