Question

Which of the following inequalities matches the graph?

Answer 1

See the line is parallel to y axis

• Means x is constant
• y is varrying

So

• x intercept is (-7,0)

X is constant -7

Hence the inequality is

• x≤-7

Answer 2

x ≤ -7

Explanation:

On the graph we can see that:

-the pink solid line is where x= -7 and y can have any value, so is either first or second choice.

-the pink area includes numbers that are equal or less then -7 ( such as -8, -9,-10,...) so the inequality must be x ≤ -7 (the second choice. )
