Which expressions are equivalent to_? Check all that apply.

Option 1. and option 4. are equivalent to

Step-by-step explanation:

Step 1:

The given expression is expanded as follows.

The -2 is multiplied with the 5x and then the -2 is multiplied with the .

So the expression becomes as follows;

This is the first option given so the first expression is equivalent.

Step 2:

Of the other four options, only the fourth expression has the fraction so the fourth expression is also equivalent.

Expressions 1 and 4 are equivalent to the given expression.

step-by-step explanation:

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)
