perp to x-3y=2 thru (2,4)
For perpendicular we swap the coefficients on x and y, negating one
3x + y = some constant
We get the constant in the obvious way from the point
3x + y = 3(2) + 4 = 6 + 4 = 10
Answer: 3x + y = 10
Answer:
To make 16 cookies you will need 1 cup of sugar.

Answer:
(3,2)
Step-by-step explanation:
The solution that satisfies both equations is where the two lines intersects.
The two graphs intersect at x=3 and y =2
What you do first is add 4 to both sides of the equation to get x alone and you get x=11. X is equal to 11.
