Linear or non linear?
2 answers:
Answer:
Linear
Step-by-step explanation:
This is linear because using the data you have provided we can work out that the equation is y= -5x+27
y= mx+ c (c is the gradient)
This equation shows that the line is straight (also shown in the picture) and therefore must make it a linear graph.
For the graph to be non linear, the graph would be curved but this would mean the equation would have to be a quadratic - which it isn't.
Hope this helps!

x is strictly less than 2 or x ∈ (-∞, 2)
Given: inequality 5x - 7 < 2x - 1
What are inequalities?
Inequalities are statements that are represented as comparison between two or more numbers or algebraic expressions.(strictly less, strictly great, greater, lesser)
Solving the given equation:
5x - 7 < 2x - 1
=> 5x - 7 - 2x < 2x - 1 - 2x
=> 3x - 7 < -1
=> 3x - 7 + 7 < -1 + 7
=> 3x < 6
=> x < 2
Therefore, x is strictly less than 2.
Hence x ∈ (-∞, 2)
