Question

2. Which equation has a graph perpendicular to the graph of 7x = 14y – 8 ? (1 point)
y = –2x – 7
y = –x + 4
y = x + 1
y = 2x + 9

Answer 1

standard equation of line is y = mx+c
put 7x = 14y -8 into standard equation

now find m (slope) of the equation
Perpendicular line have negative reciprocal slope from the givem line

so you will have
y = -1/m(x) +c

Answer 2

thats not an anwser choice

Answer 4

I am supposed to help you first. Not to give you answer directly

7x = 14y -8
7x+8 = 14y
y = (1/2)x + (4/7)
m = 1/2
prependicular slope = -2
y = mx+c
y = -2x +c
as only one option is there for -2x
so its a
