It’s D
the x in f(x) is the x axis
look at 3 in the x axis
you see that it goes up to 8 y-axis
f(3)= 8
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:
A
Step-by-step explanation:
The area in step one is
a²+b² but that does not equal (a+b)²
