2 step equations are equations that require 2 steps to solve it.
For example, 2x + 5 = 3x + 6
To solve for x, we must isolate it.
First subtract 2x on both sides, which is ONE step.
2x + 5 = 3x + 6
-2x -2x
5 = x + 6
The we must subtract 6 from both sides of the equation, which makes is the second step.
5 = x + 6
-6 -6
-1 = x
-1 would be the answer and we only used 2 steps to solve it.
The true statement about the graph's slope is (c) Its slope is zero.
<h3>How to determine the true statement?</h3>
From the question, we have:
A horizontal line is at y = 2.5.
The horizontal line implies that the cost of lunch do not change
Horizontal lines have a slope of 0
Hence, the true statement about the graph's slope is (c) Its slope is zero.
