Answer:
Step-by-step explanation:
Consider an equation:
Here, m is the slope of the line and c is the y-intercept.
Given equation is
Here, slope is
As product of slopes of two perpendicular lines is equal to , slope of the required line is
.
Let
Equation of the required line is
When we say "a is at most b" we mean that "a is less than or equal to b" or "a is not greater than b". So let's solve this problem as follows:
Step 1. Twice the difference of a number and 2
Let's call that unknown number as n. Then, twice the difference of a number and 2 is:
Step 2. Twice the difference of a number and 2 is at most -27
