Given:

The expression is

To find:

The equivalent expressions.

Solution:

We have,

In option 1,

So, the expression in option 1 is equivalent to the given expression.

Similarly,

In option 2,

So, the expression in option 2 is not equivalent to the given expression.

In option 3,

So, the expression in option 3 is not equivalent to the given expression.

In option 4,

So, the expression in option 4 is not equivalent to the given expression.

In option 5,

So, the expression in option 5 is not equivalent to the given expression.

In option 6,

So, the expression in option 6 is equivalent to the given expression.

Therefore, the correct options are 1 and 6.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
