solution set is {-2,2}
Answer:
option C
y = 2
Step-by-step explanation:
Given in the question,
a co-ordinate = (-2,2)
x = -2
y = 2
Equation of the straight line
y = mx + c
<em>here m = gradient of the line</em>
<em> c = y - intercept</em>
<em />
<h3>we know that gradient of the horizontal line = 0</h3>
plug value in the equation above
y = (0)x + 2
y = 2
