I think the answer is 2 but I'm not sure
Two lines that intersect at 90 degrees are considered perpendicular to each other.
Answer:2n + 8 = n-3
Step-by-step explanation:
Answer:
<h2>The slope m = -2</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
<em />
We have the equation in the standard form:

Convert to the slope intercept form:
<em>subtract 6x from both sides</em>
<em>divide both sides by 3</em>

slope: <em>m = -2</em>
y-intercept: <em>b = 4</em>
Answer:
it is because 20 + 20 is 40 and then 40 - 20 = 20
