Question

. Write an equation for the line parallel to y = 7x + 11 that contains P(-5, 7).

a. x - 7 = -76y + 5)
c. y - 7 = 7(x + 5)
b. y - 7 =-7(x + 5)
O
d . y + 7 = 7(x + 5)

Answer 1

a) x – 7 = -7(6y + 5)

x – 7 = -42y + -35

x – 7 + 35 = -42y

x + 28 = -42y

y = (1/42)x – 14/21

c) y – 7 = 7(x + 5)

y – 7 = 7x + 35

y = 7x + 42

b) y – 7 = -7(x + 5)

y – 7 = -7x -35

y = -7x – 28

d) y + 7 = 7(x + 5)

y + 7 = 7x + 35

y = 7x + 28
