Answer:
y+11=-
(x-4)
Step-by-step explanation:
since the equation is perpendicular to y=4x-2, m=-1/4 (negative reciprocal). (x_1,y_1)=(4,-11), plug all the values into the equation y- y_1 = m(x-x_1) and we get y+11=-
(x-4)
Horizontal line is y=a, where a is a constant (number).
We need to choose equation this type.
y= - 7, means that for all values of x y=7.
So, answer is
B. y= - 7
